I'm no expert but here's where I'd question your play...

Hand 1: Pocket Ts
You just called and let 6 players see the flop. Pocket Pairs, especially Js, Ts and 9s, will never stand on their own against 5 opponents. You have to place a decent pre-flop bet to chase many, or even take it down right then. Or if you just call 'em, play it like Pocket 2s... if you don't catch the trips, they're almost useless. But once 5 people see the flop, you're dead.

Hand 7; Flush Draw
At the turn, I'd question your raise. Calling the .50 may even be marginal since your flush-draw was to the K and not A. PLus you were playing 2, not 1 opponent.

Hand 8; KJo
You had position, a modest pre-flop raise here might have reduced the field of opponents and/or bought you a free-card at the turn with everyone checking to you. At the flop, I don't think I would have folded, with 2 overcards and a gutshot straight draw.

Hand 9; 98o, Small Blind
Personally, I'd have played this in the small blind (but would have folded to any action post-flop, even with middle pair).

Hand 11; Q3o
You're in bad position. I would fold it pre-flop. Your .30 call at the turn against a $1.26 pot with an OS draw, with one overcard, was probably OK... barely, but against 2 opponents, I might have folded here too.

Hand 14; K3o
Big-Little offsuits are just sucker traps to lose with that crappy kicker. Fold it. Notice how you made the first call, then had a raise behind you that forced a second-call. This illustrates how important your position is. And how marginal decisions can make you "leak" money.
