I would use APC220 module, if connecting to arduino, use the TX RX pins. I have two of those and can expect range up to 500 meters. I think it must be compatible with Rpi if you get a TTL to USB adapter. And to use nodes, use if statement, so that if node 1 wants to talk to node 5, send a message like 5.message here And the node 5 only receives messages if starting with 5. And yes it can send and receive
