Hand 1,
Well if we bet and are raised we have odds to call(Depending on how much you discount). we'll be getting 7:1 anyhow so 6outs+ and its a call.

Due to this i either bet(fold equity and numerous outs to improve) i bet. Although if we check we cant call a bet surely? and if we bet and are raised we must call so it might be pricey or a fold.
Edit: just read he's passive so bet and maybe fold that raise.

Hand 2,
Check - Flush completed, paired board, hardly any clean outs and vs 3guys.

Hand 3,
Bet and fold to a raise(tell them we have a queen!). The pots getting big so this is my last shot to win it. if it folds button its GOOOD.
