I think peeling one off on the flop is okay, especially since the board is full of low cards, though I wouldn't be happy if it got raised or checkraised behind me at all.

I'd probably give up on the turn. The top card just paired so you could be drawing dead (however, at the same time, if no one does have trips, your outs against a hand like A5 did just improve). Also, with so many opponents in, the chance that catching aces up on the river will give someone else a flush are better than usual. Unfortunately, the number of players in has also increased the pot size and made it tempting to call, but I still would fold.
