As many as you wish, as long as you do cross 200 amp limit
In the United States, there isn't a hard limit on how many 20 amp circuits that can be run on a 50 amp supply. This is because in most cases, especially in homes, we don't load most circuits with more than an amp or 2, even when they are protected by a 20 amp breaker. From a practical perspective you probably have a limited number of slots for breakers in your service or supply panel.
Yes, but at every reduction in wire size there has to be a breaker sized to the smaller wire size. The wire size for 100 amp panels is recommended at #3 copper conductor. From the 200 amp feeder panel you will require a 100 amp two pole breaker for each of the two 100 amp services. Keep in mind that if you run the 100 amp services close to maximum this will take away the capacity of the 200 amp service for other branch circuits coming off of it. Also keep in mind that if the panels are located, not in the same building as the 200 amp service that the 100 amp panels will be treated as separate services and will have to be constructed like a 100 amp service. This includes ground rods. Also the bonding screw will have to be removed that connects the neutral buss to the panel enclosure.
No, it is not safe or recommended to connect a 200 amp service to a 125 amp panel. The panel must be rated to match the amperage of the service to avoid overloading the panel and potential fire hazards. It is important to upgrade the panel to match the service amperage.
No, each size service needs its own meter base.
Currently, there is no manufacturer that makes a main breaker 200 amp service with built-in 200 amp ground fault circuit interrupter (GFCI) protection. GFCI protection is typically provided through individual GFCI outlets or circuit breakers installed within the electrical system.

Most houses have several circuits each with its own circuit breaker so that the power to the whole house will not all go off at the same time. Each circuit consists of a three-wire cable, live/neutral and earth. Some countries also use split-phase circuits with four wires.
Check the nameplate on the service panel. There it will tell you what the buss capacity is. On a 200 amp service nothing in the wiring configuration is allowed to be less than that the service rating. In the market there are 200 amp 42 circuit distribution panels.
A 100 amp service provides less electrical capacity than a 200 amp service for a residential electrical system. This means that a 200 amp service can handle more electrical load and is better suited for larger homes or homes with higher electricity needs.
The recommended conduit size for a 200 amp service is typically 2 inches in diameter.

The recommended aluminum wire size for a 200 amp service is typically 2/0 AWG.
For a 200 amp service, it is recommended to use a size 2/0 or larger underground wire.
For a 200 amp service, a minimum of 2/0 gauge aluminum wire should be used.
Upgrading to a 200-amp electrical service for a residential property allows for increased electrical capacity, reducing the risk of overloading circuits and potential safety hazards. It also provides the ability to power more appliances and devices simultaneously, improving overall convenience and efficiency in the home.
A #6 copper conductor is used to bond a 200 amp distribution.
No, it is not safe or recommended to connect a 200 amp service to a 125 amp panel. The panel must be rated to match the amperage of the service to avoid overloading the panel and potential fire hazards. It is important to upgrade the panel to match the service amperage.
