Listen to the published frequencies available on the webpages.

Listen to the beacon.  They both have different beacon frequencies.

Yes.  Again...Listen.

Listen, listen, listen.  The amateur payloads are part of a larger
commercial satellite.  They have good power budgets and are on all the time.
The only birds that do not seem to be on all the time are AO-10 (for obvious
reasons), AO-27 and SO-35.  Some of the digital birds are turned on and off
depending on sunlight as well.  The RS birds are always on.

????  There's only one beacon that I have ever heard.

Listen.  Listen.  Listen.  It's been in mode KA for some time and shows no
signs of ever being changed.

In addition to listening, if you can work the bird with a 15 meter input and
the uplink and downlink frequencies are in RS-13's passband, you are working
mode K on RS-13.  If you can get in with 144 MHz and every thing is in the
RS-13 passband, then you are using mode A.  If you can do both the bird is
in KA which it has been in for a long, long time.
