Yes but it's redundant and may cause unnecessary "tripping" of the circuit. The GFCI circuit breaker is intended to protect an entire receptacle circuit whereas a GFCI receptacle is designed to protect only that receptacle and any which are provided power from its load side. (downstream)
No, they are two totally different things. A GFCI must be used within 6' of any water source, when the floor is concrete, or when the outlet is located outside or under the home. An Arc Fault breaker must be used in any bedroom, or other area you live in. Not required in kitchen, or utility room.
Yes. Ground it to neutral.

A Class "A" Circuit breaker is a Ground Fault Interrupt (GFI or GFCI) breaker ."Class A" marking -- A "Class A" ground-fault device is intended to protect people. The Class A marking indicates that the trip threshold of the GFCI is between 4 mA and 6 mA. This marking may be in any location except the back.
The GFCI is sensing stray electricity. Usually, there is no GFCI connected to the pump motor. The GFCI devices would be associated with the air blower, or the lights. If it is the circuit breaker, then there may be a problem with the circulation pump or the circuit breaker itself. A qualified electrician will be able to locate and correct the electrical problem. A pool repair tech may be able to do the same and also correct the problem if it is the motor. Ken
The terminology down stream refers to an electrical circuit and where devices are connected into the circuit. In reference to the breaker that feeds the circuit everything is down stream from it. If a GFCI receptacle is added into the circuit as the first device, the GFCI can be wired to allow all of the regular receptacles to be protected down stream from that GFCI. Every device added to the circuit will be down stream from the one that is ahead of it. The only device that will not have something down stream from it will be the last device in the circuit.
Proper name is GFCI (ground fault circuit interrupter). It could be a breaker or receptacle. It's used for wet location circuits, like bathrooms, kitchens, hot tubs, outdoor
Not if the GFCI breaker is supplying the circuit you are wanting to put the GFCI receptacle into.
A GFCI device in a breaker is intended to trip the breaker open when a ground fault is sensed in the circuit that the breaker is protecting.
No, you could use a GFCI circuit breaker instead.
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 North America they are known as a GFCI. Ground Fault Circuit Interrupter breaker.
If your spa is connected with a GFCI circuit breaker you will not need the GFCI receptacle.
A GFCI breaker monitors the imbalance of current between the ungrounded (hot) and grounded (neutral) conductor of a given circuit. With the exception of small amounts of leak-age, the current returning to the power supply in a typical 2-wire circuit will be equal to the current leaving the power supply. If the difference between the current leaving and returning through the current transformer of the GFCI exceeds 5 mA (61 mA), the solid-state circuitry opens the switching contacts and de-energizes the circuit. Touch the neutral or hot and you change this current which will trip the breaker.
GFCI = Ground Fault Circuit Interrupter.

The pool light is usually on a 15 amp circuit. The breaker feeding this circuit must have a GFCI rating.
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".
