I have just thinking about a possible solution. If i have 5 RF receiver, in each RF transmitter when i put data to send, this streamed data could be headed with an identifier, such “A”, “B”, “C”, “D”, “E”. Depending of the corresponding header word, in the receiver i can split this information for get in action with his own data.

What do you think about this?

How would you exclude that two transmitter active at same time?
