My thoughts....which may not be worth crap.

Hand 1, he calls behind you both preflop and on a pretty drawless board (unless he likes suited one gappers). Best case he is floating with overcards, but he could very likely have a PP that has you beat. You could play either way, folding to a turn raise if you bet. I think I check./fold because I don't think that T will scare him all that much.

I like the second barrel in the T8 hand, but I think preflop is a raise if you are going to play, although limping isn't bad.

Hand 2, three-bets on paired boards are usually bluffs (Yeti theorem). I don't think 4 bets are. Plus he raises an amount to keep you in the hand. I think I could let this go.

I think you have to give him credit in hand 3 unless you know he will routinely float with junk.

I think TT hand is fine, but you might have more FE with a CR here?

I just call in hand 4 to see if Ollie wants to come along for the ride. Push a lot of turns. Ollie's stack is what's giving you your implied odds, but you have too good of a hand to fold to the shortstack.

Unless you know he's chasing draws in hand 5, I think I check behind.

Hand 6 is easy turn fold. You may only have 5 outs max if you are behind.

I think I check behind turn in hand 7 and call any reasonable river bet. As played you almost have to call for odds. He check raised the flop, which he could do with a lot of draws or AQ/set with the board as wet as it is. You only beat the draws right now and prolly have less equity than the draws do. Double check raise means you are definitely behind IMO but you are committed. Hopefully he has lower flush or set and you outdraw him. This PP was overplayed (sort of like I did recently )
