If by "depth" you mean the working space about a 200 amp service, it would be at least 30 inches wide or the width of the equipment (whichever is greater), by 36 inches out from the front and 6 1/2 feet high or to the top of the equipment (whichever is greater).

If you are talking about an underground service burial depth for the conduit the minimum cover is, non vehicular areas 750 volts or less 24 inches, vehicular areas 750 volts or less 36 inches

No. If device draws 200 amps breaker will trip.
No, each size service needs its own meter base.
If the mains is a 200 amp two pole breaker each leg can carry up to 200 amps in relationship to the common neutral of the service.
As many as you wish, as long as you do cross 200 amp limit

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 #6 copper conductor is used to bond a 200 amp distribution.

Yes, the wire size has to be increased. The existing 100 amp service will now probably have a #3 conductor with an insulation factor of 75 or 90 degrees C which is rated for 100 and 105 amps respectively. Increasing to a 150 amp service will use a #1/0 wire size. If you are thinking of an upgrade, skip the 150 amp service and go to a 200 amp panel. New homes are installing 200 amp 42 circuit panels. The extra cost is only reflected in the materials as the labour costs will be the same regardless whether a 150 amp or a 200 amp panel is installed. The wire size for a 200 amp panel is #3/0. With an insulation factor of 75 or 90 degrees C the rating is 200 or 210 amps respectively.
Depends on the size of the service. 100 amp service will require 3 gauge, 150 amp service will require 1/0 gauge, and 200 amp service will require 3/0 gauge.
A 200 amp service using a uffer ground will need a #3 bare copper wire. The bare copper wire is to be not less than 20 feet in length. It also has to be within 2" of the concrete foundation footing that is in direct contact with the earth. The depth can not be less than 2 feet below finished grade.

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.
The current output cannot exceed what is available. 1,000 amp service to a house is rather unreasonable and most likely would not be provided by the utility anyway. 100 amp or 200 amp service would be more likely.
