1. Check/call the flop. You have a weak draw on a coordinated board in a multiway pot. You are unlikely to eliminate another drawing hand by bettng and risk being raised.

2. You picked up a gut-shot draw on the turn, so you have more outs. Check/calling seems better than betting, because your draw is still weak and you probably dont have much fold equity against 4 opponents.

3. I would probably have check/called the river. I doubt that its worth calling the river raise, because I think its unlikely that a passive player would raise into 2 opponents without the flush.
