Yes it is a good fold. Ur almost guaranteed to be drawing to only two outs.

Preflop limping behind is fine, I would prefer raise.

Flop bet is bad. Never bet minimum for whatever reason. Always bet 1/2-pot if ur gonna bet at all. This is not an optimal flop to bet at. Check/call check/fold is fine.

Turn, it is checked to you and u bet which is horrible. With all that action on the flop and so many ppl to the turn, its almost guaranteed someone has a 9 or 8 and just boated up. Turn is definitely a check/fold.
