A double pole breaker has one pole attached to one side of your breaker panel's bus or hot leg, and another pole attached to another hot leg or bus, if it is in a residential panel (in the US) each leg of the breaker is 120 volts to ground or neutral and 240 hot leg to hot leg. The 15 amp indicates that the breaker will trip if the circuit exceeds 15 amps across the two outputs of the breaker.
Connect the incoming power to the line side of the GFCi outlet. Now run another wire connected to the line side of the GFCI outlet from the GFCI outlet to the switches. Power one of the switches and use that switch to turn on the 2 lights. Run power from that switch to another switch and use that switch to send power to the fan. Mount both switches in a double pole switch box. If the light above the sink has an outlet on it then you will have to connect power going to that light on the load side of the GFCI outlet. If not then just connect it to the line side.
I'm not positive but, as far as I know, one is required on a 120V heater but not on a 220V heater. Even if a GFCI isn't required I would install one anyway for the safety of your family and friends. These devices do work and are well worth the cost. Call a Professional... Either a GFCI outlet or a GFCI breaker, and I think I'd use the GFCI outlet because the reset on an outlet is closer to the pool than the breaker would be. But put it far enough away from the pool that you've got to get out to reset it. I think that's code; if it's not it should be.
A pole In a circut breaker refers to the number of circuts it controls, single pole only controls one, double controls 2 at same time
I would NOT do that if I were you. If someone is electrocuted and local, county or state officials discover that the GFCI has been removed, you could have some serious problems in court.If a GFCI was installed, there was a good reason for it; electricians don't put one in unless it is required by code.If you INSIST on replacing the GFCI, connect the white wire that screws into the GFCI to the neutral bar in the breaker panel and disconnect the white pigtail that comes out of the GFCI, then connect the BLACK wire to the new breaker.
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.
You need a GFCI outlet at any location that is within 6' of a water source. You also need a GFCI outlet in a room with a concrete floor, any garage, and any location outside the home or under the home in the crawl space. A GFCI outlet protects you from electrical shock near water or moisture. You can protect more than one outlet with 1 GFCI outlet. Connect the incoming power to the LINE side of the GFCI outlet and all the other outlets getting power from that outlet to the LOAD side of the GFCI outlet. That way they will all be protected by 1 GFCI. A GFCI breaker is used to protect an entire circuit and not just individual receptacles. It is often cheaper to use GFCI receptacles than a breaker, especially if "piggy-backed" such as described above. It is also more convenient to reset a GFCI receptacle than to reset a breaker. But your question is "why." From this I suspect you may be misunderstanding the difference between a breaker and GFCI protection. To keep things simple let me say that a GFCI does not work on the same principles as a standard breaker. It provides a much safer protection than a standard breaker. Even with a ground you need GFCI protection as listed above.
No, only one GFCI per circuit.

TPN means three pole with one pole neutral connected.
Yes. An everyday occurrence of this circuitry is in your kitchen counter split receptacles. The top half of the receptacle is a 15 amp circuit and from the same breaker the bottom half of the receptacle is another 15 amp circuit. A two pole single handle breaker is a common trip. If one of the circuits fed from the breaker faults the other connected circuit will shut off also. If you are talking about slot position in a breaker panel, you can remove the two pole breaker and install two single pole breakers.
A 15 amp breaker will trip at 15 amps at an ambient temperature of 104 degree F. If the ambient temperature is higher the breaker will trip before 15 amps and if the ambient temperature is lower the breaker will trip after 15 amps. I would suspect the circuit is overloaded. But, you can change the breaker and see what happens. Just swap it with another one.
The test button should only trip the GFCI. The fact that it is tripping two breakers indicates that somehow both breakers are feeding your GFCI circuit. I have seen this when there was a wiring error and two circuits were joined in an outlet that was connected to a breaker and through the GFCI outlet. To troubleshoot determine which outlets are effected when both breakers are off. Pull outlet from box and if there are two feeds remove one from outlet and run a toner on wire left on outlet to panel and one off outlet to panel. The GFCI could block the toner so if one side of the outlet does not tone back to panel check at GFCI. There must be two paths to your electric panel for the two breakers to trip and the GFCI may be faulty as well. Another way to check is to have the GFCI reset and both breakers on. Check each outlet that you have identified as being on GFCI noting that they can be in different rooms. With all outlets working turn off one of the tripped breakers. See if any outlets so off. If not turn off the other breaker and turn on the first breaker. If power is still present then the outlets are being fed by both breakers.
