thoughts on these hands

[furfur]

1)hand one u should fold preflop. too many players to act behind u and do a squeeze
2)probably just call as you'll have position. squeeze isn't bad here either but I don't know how I'd react to a rejam from original raiser so calling seems like best option
3)I can't see folding here. This guy called in small blind and while it's conceivable he did so w/ something like a,4 or 4,5s most times he has a 7 here or a pocket pair lower than you. If he had a 4, he'd be more likely to slow play and allow u to catch up. i'd rejam here and be happy about it.
4)fold preflop. I don't understand ur river raise at all. was that for value? definitely just call. Ur only beating a pair of nines here and he would probably fold it to ur raise there.
