Stream from several android phones to pc
You can use streaming apps for android which transmit the screen to a desktop-machine from which you can capture the image. I wouldn't recommend it though, as the aforementioned streaming will make your image-quality suffer big-time.

Let me propose a different solution:
using the cable of the phone in question, you can directly capture the image from the device. The only issue would be bringing the recordings in sync (if that's important). To fix this, you could open up an online clock for example which displays the exact time, so when stitching together the recordings in post, you'll be able to synchronize the recordings.
