If you mean with abridle, just not using the reins, then there really isn't a term for that. If you mean with out a bridle, the term you are looking for is bridleless.
Yes - otherwise there is nothing to attach the reins to. The horse doesnt necessarily need a bit in its mouth though.

I don't think you can buy reins sepereately from a bridle. Just buy a bridle which can be cheap if used but if you want to get one new it could be pretty expensive DON'T BUY A NEW BRIDLE IF NOT NEEDED!!! You can have reins made or a tack shop or western store will have them. They are pretty spendy they can be anywhere from $15 to $35
Hanoverian bridles have nosebands and then flash/drop nosebands. Cavesson bridles have a noseband.
It depends on what kind (the correct spelling is rein instead of reign) There are many types. There is a braided split reins, reins with rawhide braid, bitless bridle reins, a horse nylon headstall reins, rubber lined reins, camelot web reins, a barrel reins with rubber grip etc. etc.
The parts of an English bridle typically include the headpiece, browband, cheekpieces, noseband, throatlatch, and reins. These components work together to provide control and communication between the rider and the horse.
