what do the 9 friends mean on my friends box on facebook profile?

[Yesica]

So, on my box on my page I have:
1. my brother who PM me A LOT, but i rarely check his profile or picture, but we comment on updates
2. my young cousin, who kinda stalks my page and like most of my stuff and PM me a lot
3. My other cousin, we interact a TON on FB
4. my sis, we dont interact much on FB (not a reflection of our actual relationship, BTW)
5. My aunt, occasional interaction
6. My long time crush. Lots of "pokes", occasional comments and likes, some light stalking of his profile
7. a coworker, she tags me on FB sometimes and other coworker-y interactions lol
8. a friend, lots of comments and like not much PM
9. my stalker, likes my pics and PM me A LOT

^^^ so, 5 are my stated family member on my page, and the rest are what i described. Based on what my box looks like, do they mean anything? or are the random? what are they there and why do they not change (except for the last three, but havent for some time)?

those are the 9 people you have the most in common with

it has nothing to do with them looking at your profile tho, if that's what you are wondering
