Can you easily switch these from surround mode to stand alone mode?

On your cellphone you set up the speakers using the musiccast app. Once they are linked to your internet modem/AP you can quickly switch from linked mode [stereo] to individual all within thr phone app.

Will the musiccast 20 speakers work with the rx-v683 receiver?

heres the link to answer your question , https://usa.yamaha.com/products/contents/audio_visual/musiccast/musiccast-compatiblity.html ... the rx-v 683 will work but not as surround speaker

Is this just one speaker or two? Looking for wireless rear speakers for surround sound setup.

This is for one speaker. If you’re looking for a wireless surround setup, make sure your receiver supports it. The current 2018 Yamaha receivers are the only ones that support MusicCast Surround. I bought my receiver late last year (the RX-A1060) and it only supports wireless sync, not wireless surround.

Would these work as wireless rear speakers with a Yamaha AV receiver for a surround system?

You mean rear, as in 7.1? No. You can use them as surround speakers in a 5.1 system, which is how I am using them.
