Both of these really depend on the target you're planning to use. In
my experience adb/fastboot usually require more resources. We try to
aim at one physical CPU core per device in such situation. If you
don't plan to use adb/fastboot you don't need as much. As for master
it should be able to deal with the amount of logs your jobs generate.
If you don't have very long logs, then master doesn't need to be very
powerful. However it's worth looking ahead and preparing to expand the
lab. So more powerful master should be considered. You can also think
about hosting your master in the cloud. This gives you even more
flexibility.

The sky is the limit here. You can use GPIO relay with RPi[1],
ethernet relay[2], managed PDU [3] or something else as long as it can
be controlled remotely by software.

hmm, do you mean serial concentrator? How do you connect to UART on your boards?
