Yes, as you enter them into BIAB, and they are all converted to a 2 chord. But No, as far as classical theory, where the meaning of the four chords I gave is different for each. Don't forget, you may hear any of the four being played by a RealTrack artist.

And if you mean, are there other ways to enter C7+ into BIAB? Yes. C7#5 or C7aug (which isn't on the 2018 chart).

C9+ is also possible by C9#5 but C9aug does not work.

I can't wait for the next question, about Bflat9 versus Bnatural with a flatted nine...
