Annabelle - I think... they would get along splendidly considering the similarity in their personalities. Arden needs a few more close friends, so maybe she could be one of them. It'd make sense.
Alecto - Arden would be familiar with her and along with that familiarity will come respect. I don't know if they'll get much of a chance to interact, but she'll be pleasant more or less.
Tracey - Can't blame her for the fear, but Arden's not so bad most of the time. As long as you're not on her hit list, then there's absolutely nothing to worry about. Anyway, they're part of the same House, so she'll be pretty okay around her.
Susan - I wouldn't be surprised if snark happens. But, all in all, Arden doesn't have much of an opinion concerning Susan. Just another Half-blood. I wouldn't put it past her to visit her pub disregarding whether she's welcomed or not.
