there should be 5 wires, hot and switched hot for the switch and hot, neutral and ground for the gfci receptacle.

Why are wires twisted together on a GFCI outlet box?
The ground wires are twisted together and then connected to the GFCI ground. The black and white wires may also be twisted together and then using a jumper wire connected to the GFCI. Hard to say without seeing exactly how it is wired.
Will a gfci breaker work when neutrals and grounds are together in main panel or will there have to be a separate ground bar installed and wires separated?
Yes a GFCI will work if the neutrals and ground are to together the main panel. This is considered the line side of feed side of the GFCI. Neutral and ground can not touch down stream from the GFCI or on the load side of the GFCI.
What would be the correct wiring for 3 sets of wires into a GFCI outlet?
I'm assuming your 3 sets of wires are black or red, or some other color normally associated with the "hot" wire, a white for neutral and a green or bare conductor for ground. If your GFCI protects only itself and no other receptacles, you splice all the wires of the same color together and attach 'pig tails' to your splice to connect to the GFCI. If your GFCI protects other receptacles 'down stream', you connect only the hot and neutral feed from the panel to the line side of the receptacle. Then you splice the others together as described above and connect your pig tails to the load side. "Line" and "load" should be clearly marked on the GFCI. Your ground in this case is still all spliced together with a pigtail for connection to the GFCI. Line is from the panel. Load is to other receptacles. Getting these reversed will prohibit your GFCI from functioning properly.
What is a gfci oulet?
GFCI=Ground Fault Circuit InterrupterIt's an electronic circuit breaker that compares the current on two wires. If the current is NOT equal, the breaker trips and does so quickly enough to prevent electrocution in the event of a "ground fault".
What happens when you plug a GFCI protected extension cord into an outlet that is GFCI protected?
In a word NO, that will not cause either GFCI to trip. The correct term is GFCI (Ground Fault Circuit Interrupter)

What can you do if your newly installed GFCI keeps tripping unless you detach all the other outlets in the room but all outlets are wired correctly?
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.
The GFCI outlet's reset button does not pop out when the test button is pressed it is already out and when I try to press it in it will not catch although it does have power?
This indicates either you have an active ground fault or the GFCI is bad. To check this out turn off power at breaker and remove GFCI outlet from wall box. Determine if it is powering other non-GFCI outlets. (It will have both input and output wires. If there are output wires remove them and check the outlet again with power and see if it resets. If it does you have a ground fault down the line somewhere. If it still doesn't work you likely have a bad GFCI.
Can you have two bathrooms on one run?
Yes. Also on GFCI you can run output to second bathroom outlet and will be protected. Great thanks. That make more since, because there's only four outlets for both plus the lights on a 20a run Is it considered better to run the circuit through one GFCI outlet or is that to cut cost. I don't mind buying four GFCI outlets and adding the extra pig tail wires, specially if it might work better

How do you wire a GFCI if there are 2 black wires?
You will have to run new electrical wire or a single ground wire back to the panel (though the former is highly recommended). A GFCI outlet will cut off the circuit if it senses voltage leaking to ground. If there is no ground wire, it will not function.
Do you need a gfci outlet if you have a gfci breaker?
Not if the GFCI breaker is supplying the circuit you are wanting to put the GFCI receptacle into.
Do you wire a gfci outlet differently?
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.
How do you reset a GFI?
To reset a GFCI you need to first correct any ground faults in the circuit - or some other other fault in the equipment and/or its flexible cord and/or its plug - being protected by the GFCI, which is causing an imbalance in the currents flowing in the hot and neutral wires. Ground faults are usually caused by wet electrical equipment. Then you need to press the RESET button on the GFCI.
Can you use a GFCI plug into a GFCI outlet?
Yes you can. Lots of blow dryers have GFCI protection built in.
