Yes, you install a GFCI on a 2 wire circuit.
To install a GFCI breaker in a circuit, first turn off the power to the circuit at the main electrical panel. Remove the panel cover and locate the circuit breaker that needs to be replaced with the GFCI breaker. Disconnect the wires from the existing breaker and connect them to the new GFCI breaker according to the manufacturer's instructions. Secure the GFCI breaker in place and replace the panel cover. Turn the power back on and test the GFCI breaker to ensure it is working properly.
To safely install 2 GFCI outlets on the same circuit, you should connect the line wires from the circuit to the line terminals on the first GFCI outlet, then use additional wires to connect the load terminals of the first GFCI outlet to the line terminals of the second GFCI outlet. Make sure to follow the manufacturer's instructions and consult a licensed electrician if needed.
To install a GFCI in a 3-way switch circuit, you will need to replace one of the existing switches with a GFCI outlet. Make sure to turn off the power to the circuit before starting the installation. Follow the manufacturer's instructions for wiring the GFCI outlet properly, and test it to ensure it is working correctly before turning the power back on.
Typically, you can install multiple GFCI outlets on one circuit, but it is recommended to consult with a licensed electrician to ensure proper installation and safety.

To safely install multiple GFCI outlets on the same circuit, you should connect the line side of each GFCI outlet to the circuit's power source and then connect the load side of each GFCI outlet to the next outlet in the circuit. This will provide individual protection for each outlet while ensuring proper functionality. It is important to follow the manufacturer's instructions and consult a licensed electrician if needed to ensure proper installation and safety.
To add a GFCI outlet to an existing circuit, first turn off the power to the circuit at the breaker box. Remove the existing outlet and connect the GFCI outlet's line and load wires to the corresponding wires in the circuit.

Not if the GFCI breaker is supplying the circuit you are wanting to put the GFCI receptacle into.
A GFCI can detect ground faults on the specific circuit it is connected to. If multiple outlets are on the same circuit protected by a single GFCI outlet, the GFCI can protect all of them. However, if the outlets are on different circuits or not downstream from the GFCI, they would need their own GFCI protection.
