Hand 1) I do the same, prob fine

Hand 2) Tough one. I like to think I pay attention to the other players so if I was villain, I would have a hard time believing that you completed your straight. You raised pf w/ limpers so what hole cards would you do that with that complete the straight? AQ? maybe KQ? not a lot so I would have a hard time believing this bluff. I give up on turn, he has position and the card completes what he possibly holds.

Hand 3) He 3bet on flop so I dont know what kind of fold equity you have. If you have FE, why go all in? just pop it to $1.60- $2 and see.
Ih he just calls that, then you can maybe put him on a worse FD or TP, 2P type hand.

Hand 4) Flop is fine. I still bet turn for value (maybe 1/2 pot) and c/f river.

Hand 5) Folding preflop is fine. You were likely a coinflip with JJ-QQ and in bad shape with KK, AK, AA.
Sorry man but this was spew on turn....he didnt 3bet with a worse Ace so you have zero fold equity and you wont win in a showdown at this point. Given your flop call the turn is a fold. He is showing a huge amount of interest in winning this hand and building the pot.

Hand 6) 3bet is fine although calling and bringing in a large portion of his range isnt bad either. Since you are OOP I prob 3bet as well.
On flop Vs a loose player like this I still bet turn as he can continue with worse.
I like your river decision

Hand 7) IDK....
vs unkowns I call pre vs loose fish 3bet pre is possible to keep field low.
Flop I raise about $1 vs 2 opps with FD out there. Turn is fine. Your river bet is weak. I check behind on river, the pot is already pretty big for just TP and now the FD completes which he was very capable of calling down for. Tough for him to call with a hand that you beat...
