I'd probably get along well with the three girls and Ueda. Just because they're cheerful (...when not emoing, uh) and I'm pretty cheerful. IDK if we'd be close, but we'd at least be friendly to one another.
I'd probably think little!kuro is damn adorable and a grumpy kid (since he would remind me of my brother, I'm sure) but I don't think he'd like me very much. He'd find me far too passive aggressive and flighty.
