for sonar, you really only want 1 sensor transmitting its audio at a time, or else the other sonars will get confused as to whether it was their audio being reflected back, or someone elses. this means you need 2-way radios in order to coordinate, or some other way to coordinate them like an IR transmitter (IR would be another way of transferring data as well). so using a single frequency is fine, since they will only be talking one at a time.
you will need an arduino per sensor in order to encode the data and do the synchronization. there might be some way around this with an encoder chip or RF with built in encoder, but the sonar modules would have to be very simple in order to allow for that. but, if possible, i would reccomend running very small wires and hiding them in the cieling or something.
