Thanks, djjaguar64!
I played around with it a bit more, and AC led into US Airways, and I selected my US Airways' seat and its unique pnr was available to view.
AC's 0014#, plus my full name, flight number, and flight date got me into NH's system. NH then generated its pnr as well.
Only TG and SQ remain. TG flight is an A380 F seat, and SQ is a two-hour flight on a 333 J, so I'm not too worried about the latter. I then tried combinations of all the PNRs on hand, to no avail, so I will just call it in. I know it'll work for SQ over the phone; just have to find a few minutes of free time.
