Ok, maybe I found something to explain at least the RCH birds. Everything around the Middle East from the US starts with RCH in its callsign. That must mean all these transports are part of the same overall mission in Afghanistan to get people out of there and back stateside. Just the back and forth hops from AFG to Germany or UAE, then hops back to the US. Everything in that mission probably shares callsigns so they can track by the 3 digit number.
But then what about the 737/C130 sharing callsigns (not RCH) and then the Beech 90's being the same but seemingly out of different places?

RCH is common for the transports stands for "REACH"
