Your question :"Can my teammates grab different radios and still connect?"
Yes, You should be able to as most GMRS radios have all the same radio bands as per channel or so. The UHF radio's can be programmed fairly easy to each channel of the GMRS Frequency's so you can connect without any problems. Some where on ASC is an list of the frequency's for GMRS channels ,but I can't remember where is was.
