I haven't played long with either CO or BTN in this hand, so don't have much by way of reads. Both players appear a bit fishy, though not complete and utter spazzes. That's about all I can say, other than I do think one of them would have raised TT+ pf (they're both limping in sometimes, but I have seen them both raise pf before).

Again, converter not working for me, sorry.....

First off, have I played the hand standard thus far?

As to the decision, I'm getting nearly 7:1 [after rake], though not closing the action. Best case, he's getting rammy with a draw; worst case he's got something like Ax and I'm now drawing dead. Alternately he could have 9x that he feels better about since the ace paired; if so, he's likely got me out-kicked, though may be a fair chance of the river card allowing a chop.
What should I do?

bet-fold is ok for me. Raising with flopped draw on the turn... against two guys... It must be a specific opponent. And people mind the ace. Ace is the ace. You know.
And we shouldn't forget the CO.

You're basically hoping for a parlay of both players being on draws at this point. Even if button only has 9x, at best you're hoping for a chop. Bet-fold seems right here.

(If it were heads up, I'd have to at least think for a bit before probably folding. In a protected pot, I don't hesitate at all.)

I'd probably try to xr the flop tbh, I expect a lot of weak stabs from button (the limp pre stab flop line is what I call the fish power move btw).

On turn, I mean...meh. Both opponents passively played flop, but it's hard to have both beat right now. Calling a raise would be bad after this action.
