Sure but go for a 200 amp box if you are certain your incoming power supply cable from the street can support it. You should always check with your local electric power company before you upgrade any main supply panel or breakers.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

You would have to ensure that the service entrance cable can support 100A. Depending where you are located, you should inquire of your electricity provider if you are equipped for 100A. It may also require a meter change out.
Not that I know of. The largest GFCI breaker I have seen is a 60 amp.
I doubt if the 125 amp breaker will fit into a 100 amp box. This is due to the rating of the box only being rated at 100 amps. If this exchange could be made then the service conductors feeding the box must be upgraded to take the 125 amperage that the breaker will allow on the conductor.
Depends on the size of the wire going to the A/C. If the wire is AWG #10 you cannot install a 40 amp breaker. If the wire is AWG #8 you can.
Yes.Additional InformationBreakers and fuses protect the wires to prevent fire. The 100 Amp breaker in the meter base (main) protects the wire from the meter base to the breaker panel. The 50 Amp breaker in the breaker panel protects the wire from the breaker panel to the outlet. Sometimes the 100 amp main breaker is located in the panel.If you are asking "Can you use two 50 amp breakers for the main breakers with a 100 amp service, then yes you can. The National Electrical Code allows you to use up to 6 breakers as the main overcurrent protection.
No. If device draws 200 amps breaker will trip.
The amperage capacity of the main bus bars and the connection of the main breaker to the bus bars.
NO!
Replace the 30 Amp Breaker with a 15 Amp breaker.
A 100-A sub-panel would be fed from a 100-A breaker.

No, a double pole 50 amp breaker protects a 240 volt supply at 50 amps. The number that is on the handle of the breaker is the amperage that the breaker will trip at if an overload occurs on the circuit.
A #3 copper conductor with an insulation factor of 90 degrees C is rated at 115 amps. Even though the panel is rated at a higher amperage it is the main breaker that governs the wire size.
