   Yes.

   If you can copy two signals on two different "channels", you should 
   enter as 2R. I hate to use the word "channels" with amateur radio, 
   but it fits. A RTTY channel is no more than 300 Hz wide.

I actually don't think #3 is workable.  It may be for RTTY, but for CW
or PSK31 it's certainly possible to recieve multiple streams, even
with the narrowest bandwidth available (my computer can sometimes copy
two PSK31 signals even with the bandwidth of my 756PRO cranked down to
50Hz bandwidth).

If you can RX while transmitting, then you're in the 2R category.
