how many concurrent device instances can I have with the free desktop license

There is no hard limit on the number of Genymotion Desktop devices you can run simultaneously. It is not recommended to run more than one at a time, and running more than two can cause major performance loss and instability.

If you want, I can also tell you which free-version features are disabled when you run multiple devices.
