A sister is a woman or girl who has the same parents as you.
A cousin is, in its strictest sense, someone who shares a set of your grandparents, but not your parents. They're the child of the brother or sister of your parents.
Twins are two children born at the same time. The mother was pregnant with both at once.
My guess reading this comment out of context is that Folklore and Evermore are very similar, but ttpd and midnights are basically the same.

Sisters: girls with the same parents
Twins: children who not only have the same parents but also come from the same pregnancy. Girl twins are sisters, but not all sisters are twins. Twins also stereotypically look identical, but there are different types of twins who don't look similar at all. "Sisters, not twins" is a phrase that means "these two things are similar but not identical"
Cousins: children who share grandparents but not parents. The children of your aunt/Uncle are your cousins. This is also a gender neutral word

In this context, it’s a way of saying how similar the albums are to each other. Twins are most closely related, then sisters, then cousins.

They are being used to express degrees of similarity. Twins being virtually identical, and sisters slightly less so. Cousins would be related but only share a passing resemblance. In the context of albums, it would mean that the two things being compared either sound similar or have shared themes.
Another example of this is when people talk about making their eyeliner match on both sides. You may hear the expression "sisters, not twins" to mean that they should look similar but not identical.

people have explained the familial meanings, but in the context of Taylor Swift albums:
they're saying Folklore and Evermore are similar, but different. they're "related." they share a resemblance, but you'd never confuse one for the other.
and there saying that The Tortured Poets Department (abbreviated here as ttpd) and Midnight are almost exactly the same. they much more closely resemble one another than the other two.

r/TaylorSwift can certainly explain this better in this context

I'm guessing they are saying Folklore and Evermore are very much alike (like sisters) but TTPD and Midnights are exactly the same (like identical twins).
Sisters - siblings born at different times by the same parents
Twins - siblings born at the same time
Cousins - people with parents who are siblings

if you don’t know these words it may be difficult to explain without using other family words. i wish we could just post a chart

I don’t know much about Taylor Swift or her music, but I do know that she tends to tell a story with her albums. I would imagine that two of her albums being “sisters” or “cousins” means that they aren’t the same story, but they take place in the same continuity.

Sisters are two women are related by the same two parents
Twins are two people who are born at the same time to the same parents
Cousins are two individuals who are related by another family members child. For example, your mother's brother son would be your cousin.

Sisters = humans with vaginas popped out of a single woman (doesn't matter how long in between). The offspring are sisters to each other
Twins = humans (regardless of what's between their legs) were pooped out of a woman at pretty much the same time (like at max a day or so, usually minutes apart)
Cousins: You had a kid. Your sister (defined earlier) or brother (male sister) had kid(s). Your offspring is a cousin of their offspring.

A sister is a female sibling. Siblings share parents. Brother is a male sibling. A half sibling only shares one parent, and a step sibling shares neither parent, but their parents later got married.
Twins are siblings born at the same time, the mother is pregnant with both at once.
Cousins share grandparents, but not parents

cousins are people who are not brothers or sisters that share an ancestor. technically all people that share an ancestor are cousins, but in practice we only go back a few generations. First cousins share a grandparent. My dads first cousins are my first cousins one generation removed, their children are my second cousins. After third cousins, we stop thinking of them as cousins. It's kind of wild that everyone is defining cousin as first cousin to me, but maybe you guys didn't have family gatherings multiple times a year with your second cousins like I did.
sisters are girls that share a parent or more.
Twins are brothers and sisters that are born on the same day to the same mother. People often say twins to mean identical twins, which are the twins that look exactly alike.

I have no clue what this means when talking about Taylor Swift albums--this seems to be some kind of slang specific to her fandom and being a native speaker does not help me understand.
If you're not generally familiar with the way these words are defined, twins are siblings who are born from the same pregnancy, sisters are female siblings, and cousin is a generic word for any relative who is not your direct ancestor or descendant, sibling, descendant of a sibling, or sibling to one of your direct ancestors or descendants (most often we use it to stand in for the more specific term "first cousin", which is the child of one of your parents' siblings).
If I had to take a guess about what these terms mean in the Taylor Swift fandom, I would imagine they're using a family metaphor to describe how closely related the albums are to each other, with cousins being the least closely related, sisters being more closely related than that, and twins being the most closely related.

Others have expressed the difference but I wanted to point out in English there are two forms of twins: Identical twins and fraternal (or non-identical) twins.
I point this out in case your native tongue has specific single word nouns to distinguish these.
Cousins can be termed as 1st, 2nd, 3rd, etc. and once, twice, three-times, etc. 'removed'.
Cousins (first cousins) is where you share grandparents, so they'll be children of a sibling (brother or sister) of one of your parents. Second cousins is where you share great-grandparents, meaning your second cousin will have a parent who is a cousin of your parent. Third cousins share great-great-grandparents etc.
Cousins are 'removed' if they are one or more generations removed from your own within the family tree. e.g. my relationship with my mum's first cousin is that we are both "first cousins once removed". And my daughter's relationship with them is that they are both "first cousins twice removed" because that cousin is now of the grandparental generation with respect to my daughter.

Sister: A girl who shares the same parents
Twin: A brother or sister born at the same time
Cousin: A child of one of your parents siblings. Shares the same grandparents as you.

The implication here is probably identical twins. Fraternal twins are no more genetically alike than regular siblings.
profuselystrangeII•
It is reminiscent of how people talk about doing their eyebrows- they’ll say eyebrows are “sisters, not twins,” meaning that they are supposed to look similar but not identical.

As a native English swiftie, and I am also confused by the claim ttpd and midnights are twins! Everyone else is right about what they think the op means, you aren't missing anything if you disagree with op

Tangent: If you see the term "Irish Twins", which has some loaded context. It will refer to siblings that are born within the same year but not actually twins.
