There are tow places to put a Ground Fault Circuit Interrupter. There is a GFCI breaker which would be installed in a breaker box and a GFCI outlet that can be installed anywhere. Most GFCI outlets allow you to connect regular outlets to the GFCI and those outlets will also be protected.
Don't know what you mean by back wire, but most GFCI outlets have a circuit to attach additional outlets that will be protected by the GFCI. Keep total load in minds.
Is the GFCI wired correctly. Voltage in goes to LINE. Voltage out goes to LOAD. Ground wires connect together and connected to ground on GFCI. All screws tight. If all this is correct and you have no loose wires on any of the outlets and no wires are shorted out in any of the outlets then more than likely you have a defective GFCI. Replace it with another one. I get bad ones all the time.
No, except that you insert the wires into the holes on the back of the outlet. The power in connects to the LINE side of the outlet and power out connects to the LOAD side of the outlet. This is clearly marked on the back of the outlet. This will not only protect the outlet with the GFCI installed but all outlets receiving their power from that GFCI. If you do not want to protect the outlets receiving power from the outlet then connect that outgoing wire to the LINE side also. But know that only the outlet with the GFCI will be protected and all other outlets will not be GFCI protected.
Your question is a bit vague, but let's try a two part answer. If you have a GFCI breaker in an electric panel you should only have one connection at the breaker, but the breaker will protect all devices on the circuit. If you are talking about a GFCI outlet, they are equipped to extend the GFCI protection to other non-GFCI outlets by using the proper "output" connection on the GFCI.
GFCI Breakers are quite a bit more expensive than a GFCI outlet. More often than not a typical residence will need only a handful of GFCI outlets that combined together will be cheaper than a GFCI breaker. If you need to protect a series of outlets with GFCI protection you can simply connect the rest of the outlets on that same circuit downstream from the first outlet on the line and make that the GFCI. All you have to do is connect all the other outlets to the LOAD side of the GFCI outlet. If a GFCI fault occurs in any of the outlets down stream they will trip that very first GFCI plug you placed and keep you safe.
A GFCI can detect ground faults on the specific circuit it is connected to. If multiple outlets are on the same circuit protected by a single GFCI outlet, the GFCI can protect all of them. However, if the outlets are on different circuits or not downstream from the GFCI, they would need their own GFCI protection.
It is recommended to have GFCI protection for all electrical outlets in a garage to help reduce the risk of electric shocks. This would typically involve installing a GFCI outlet at the beginning of the circuit to protect the rest of the outlets downstream.

No, it can be on a circuit with conventional outlets.

Yes, you can install GFCI outlets in the two bathrooms fed by the line from the GFCI outlet outside. It is a good safety practice to have GFCI protection in bathrooms to help prevent electrical shocks. Make sure to follow proper installation procedures and consult a licensed electrician if needed.
GFCI outlets should be tested monthly to ensure they are working properly. This can be done by pressing the "Test" and then "Reset" buttons on the outlet. If the GFCI does not trip when tested, it may need to be replaced.
Two 20 Amp circuits with the outlets staggered so a different circuit is on two adjacent outlets. Should be GFCI protected.
