Orange Pi is a controller and not a gateway. If you are suggesting you want to use the 5v adapter to power both controller and gateway I can not answer you. It might work but in the same time it might be to weak or to much interference. Try! If you get alof of random freezes and/or bad network communication you might want to seperate them
It might work - but using the nrf24l01+ amplified requiers some more juice than then pro mini/uno/nano can handle so I suggest using a power in with a good voltage regulator (that can provide high current) and then split of to each unit.
