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.
Yes, you install a GFCI on a 2 wire circuit.
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.
Not if the GFCI breaker is supplying the circuit you are wanting to put the GFCI receptacle into.
Deoends on code you are governed by. In USA, a GFCI outlet or a circuit controlled by a GFCI circuit breaker would be required.
The term GFCI stands for Ground Fault Circuit Interrupter.

An ELCB (Earth Leakage Circuit Breaker) distribution box is a type of electrical box that is used for electrical GFCI (Ground Fault Circuit Interrupter) outlets. This is the type of outlet that requires a three-prong plug in, one wire of which is grounded. GFCI outlets are set up so that if there is a circuit overload, the outlet is shut off until it is reset, manually.

No, it can be on a circuit with conventional outlets.
No, you could use a GFCI circuit breaker instead.
If your spa is connected with a GFCI circuit breaker you will not need the GFCI receptacle.

I don't know if you are trying to ask if you can run a 240V panel off a GFCI or run a 120 V sub panel off of a GFCI. Can you clarify please,,,Thanks
A "GFCI" is a ground fault circuit interrupter. For more information see the link below.
