Sort of... there are plenty of people in the FF's I don't think I'd get along with. That's why they're not on the list. After all, all I have to do is look up any title on wiki to get the names and personalities so it's not like I don't know who's in a game just because I haven't played it much.
Jecht reminds me of my ex's dad (I was forced to get along with him). I don't know what Garland or Kefka were like pre-psycho. Squall and Cloud like to play the silent-loner type, but at least they talk sometimes. Shadow doesn't really which is why (like Snake Eyes from GI), I wouldn't be able to hang out with him, unless he turned out to like video games. I can hang out with anyone to play a game or watch a movie. I'm not really big on conversation but there's not much point to being around someone who never says or does a damned thing.
Palom reminds me of my younger cousins most of whom I get along with well enough and usually want my attention which is always a plus.
I'll add Denzel, Marlene, and Tidus.
I'm fairly certain now that pre-journey Lulu, Lightning, and Ashe would not be hospitable. I would likely still try to get in Lulu's graces because I admire her... gifts. Also, I'd still try to befriend Cloud despite his stand-offishness because I've always imagined him to be similar to my brother.
