Hand 1 I'd just call cuz I'm a wuss. But I think it's close and your line is fine too.

Hand 2: I think he open limped a big ace. I'd check-fold the turn rather than spew to a gutshot.

Hand 3: He's either stringing you along with a monster like J2 or Q2 since he puts you on Ace-rag or a low pocket pair that he's afraid will lose to your Q or J. I think you played it fine. I would call a river raise but I wouldn't like it.
