Hand 1 fold flop its a really weak draw and if you hit it its still vulnerable

Hand 2: up to the turn play is fine im not sure about the river bet though you really have to think about what hes calling you down with is it a draw or is he calling with something like 99 or AJ or A10 something marginal that if hes called bets on the flop and the turn hes probably not folding the river getting almost 3-1 or he could be slowplaying 55 or 101o even.

Hand 3: folding preflop for sure im not calling a preflop raise with 107 even if its suited and in position, fold and find a better spot.
