A 100-A sub-panel would be fed from a 100-A breaker.
Yes as long as you change the 50 amp breaker to a 15 amp breaker. You will be hard pressed to get the 50 amp #6 wire under the terminals of the 15 amp receptacle.
Yes, but they obviously cannot be simultaneously loaded their maximum loads because the 400-amp breaker will blow well before that. Similarly, you can have multiple 100-amp panels fed from a 200-Amp main breaker, knowing that you will NEVER have 100 amps running in all panels at the same time.
You can reduce the breaker size because that limits the current that can reach the main panel. There is no safety issue other than the significant danger in an unskilled person changing out a main breaker.
Not unless you change the wiring for that circuit. The breaker protects the wiring and if you install a 40 amp breaker on a 15 amp wire circuit you will have a fire in your home.

Not that I know of. The largest GFCI breaker I have seen is a 60 amp.
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 there are no adapters made for these types of installations. The reason there are no adapters is to provide a factor of safety. To plug a 30 amp plug into a 50 amp receptacle could allow 50 amps to be applied to a 30 amp rated cord. The 50 amp receptacle is more than likely being fed by a 40 amp breaker. Just change the plug cord to match the ampacity of the breaker ahead of the 50 amp receptacle. Or change the 50 amp receptacle and 40 amp breaker to a 30 amp breaker and use your existing cord plug.

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.
probally about 100 dollars
If a 100 amp breaker keeps tripping there is an overload on the system.
A 30 amp breaker is designed to trip at an earlier point than a larger 40 amp breaker so one appliance that operates on lower amperage level could be unsafe or damaged before it could trip the higher 40 amp breaker. Also, the existing wiring may not be rated for 40 amp service.
