I'll throw a quick reply up but let some others chime in:

hand1: pretty much just a cooler if he had QQ. 3bets preflop you have to be careful but it's so weak and you hit your hand on the turn, you did good getting it in

hand 2: probably fine. min raise screams good hands a lot but you have a lot of outs here. In general I'd probably just call the flop reraise to see a turn and see what it brings, but I'm bad at pushing hands like this where I have no made hand but am ahead in equity vs villains range. So I'm not sure what to tell you about your flop push.

hand 3: I have a real hard time raising vs. so many limpers without a better hand. I probably limp behind here just because I end up building a much larger pot than I wanted preflop with a mediocre hand. As played, flop bet is weak. I'd make it more like .40-.45(pot of .51). I'm not sure how excited I am about 2barreling here because we're basically committing ourselves. Depending on what we think of vill's range I'm either shoving turn (since there's only .50 left after subtracting the pot) or checking behind. Typically I'd check behind for pot control reasons here.
As played I think you're probably behind but it feels so wrong to fold when you already have 2/3 of your stack in. Use your bet sizes to keep you from getting into these spots.

hand 4: I think is pretty fine
