I believe they are all BaoFeng UV-5R+/UV5R.

They were recommended for us when off roading to communicate between vehicles, but never seemed to work great at that.

Somewhere I think I still have the usb programming cable for them.

Edit: apparently the intent of my post was lost in my poor wording of the title. It has been updated to better reflect that I would like to use them, but for what? And how?
