Since you now have codes for all 3 cyl on bank 2, swapping a coil on the same side will not prove anything. You'll need to swap it to bank 1 for an effective test. Clean up the plug you took out and put it back in the original cyl you took it out of. It sounds like you just threw a random spark plug into your car and that's not good.

Bad gas would not selectively choose to foul just bank 2 cyls.
