GFCI's are not used to protect a switch they are used to protect an outlet where something is plugged in.
Not if the GFCI breaker is supplying the circuit you are wanting to put the GFCI receptacle into.
Yes
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.
Deoends on code you are governed by. In USA, a GFCI outlet or a circuit controlled by a GFCI circuit breaker would be required.

In rooms without exposure to water such as a bedroom or living room. Typically, GFCI is used in bathrooms, kitchens, garages, outdoors and sometimes basements.
Yes
Yes you can. Lots of blow dryers have GFCI protection built in.
In a word NO, that will not cause either GFCI to trip. The correct term is GFCI (Ground Fault Circuit Interrupter)
Since GFCI's are more expensive, you wouldn't want to use them in any place where they are not required. In many old homes, GFCI's are sometimes used for outlets in bedrooms and living rooms where proper grounding is necessary (for computers, TV's, other electronics), but not available because of the age of the wiring. You would also want to avoid cramming a GFCI into a box that is too small to accommodate the bulkier GFCI outlet. You should first replace the box to a larger one.
my gfci trips when my christmas lights r on and it rains is the gfci bad or is this normal of a perfectly working gfci
yes wind can be used everywhere!!
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.

The trip time for a GFCI is from 15 to 30 milliseconds.
