I've got my eight here. With Hanna Marin from PLL on hold.
For Suze I can see PJ being friendly and kind of amused by her. PJ is a cupid-witch and supernatural people be friendly! Lydia will be interested in what she does and probably accidentally call her Cora a few times. Newt will be friendly. Liss could be friendly as well! Sam with Tai and really all of the above.
For Lily - She's welcome to the BATD of course, which means Lissa would know her pretty well given that she's pretty high up in that world and helps to organize everything for it. Alicia is from her world and I always picture still keeping in touch with WEasley family folks so it's likely Lily grew up knowing an older Alicia. Otherwise any of mine are up for plot of course!
