The thickness of subfloor needed generally depends on how far apart your floor joists are located. In most cases, floor joists are 16" center-to-center and the most common thickness of subfloor is 3/4". Some homes will have 1/2". If your floor joists are farther apart, you will need correspondingly thicker subfloor to adequately support weight between the wider joists. Your city's building codes department will be able to specify what you need (some cities may have differing requirements).
Another factor might be the kind of flooring you will install. For carpet, vinyl, laminate, wood and other non-rigid flooring types, the 1/2" or 3/4" will be adequate. For tile, the Tile Institute of America recommends no less than 3/4" subfloor on 16" centers floor joists - but with 1/4" backerboard installed on top of subfloor. See their website or contact your city codes department for specifics on a different span of joists.

The sub-grade's compacted soil, topped by the sub-base of crushed stone and then the pea gravel.
There is no simple answer to that. Newer homes will typically have 3/4" subfloors. The total thickness with the flooring on top not included. In older homes wood floors it is not on common to see floors as thick as 1 1/4".
The bulk density of screed is 22KN/m³. Simply multiply by the thickness to get a weight. 22kN/m³ = 22000N/m³ 1 Newton = Mass x Acceleration = kg * g (g is acceleration due to gravity) On earth g is 9.8 22000N/m³ = 2245kg/m³ You then multiply this by the thickness to get the surface mass. Say it is 50mm 2245kg/m³ x 0.005m = 112.25kg/m² You then multiply this by the area of the floor to get the total floor weight. If you have 100m² floor area then 112.25kg/m² x 100m² = 11225kg
You shouldn't. You need a surface that will allow the adhesive to make a good bond to. There are different types, read the instructions for the one you buy and apply it to the recommended sub floor.
Generally speaking, the thickness of the plywood layed directly over floor joist.
A subfloor is a structural layer that provides a base for finish flooring to be installed on top of it. It is typically made of plywood or oriented strand board (OSB) and provides a flat, level surface for the finish flooring to sit on. The subfloor helps support the weight of the flooring, distributes loads, and helps with insulation and soundproofing.

Usually yes, a well insulated sub-floor will save you lots of money from heating. You can choose to build a sub-floor on 2x4 lumber with moisture barrier or use those sub-floor tiles (usually come in as 2x2).
Not usually, no. As long as the sub floor is solid, without water damage, etc then a backer board is usually plenty. You need to have 1 1/4" of sub floor and backer board when you put the tile down. Generally speaking, homes are built with at least a 3/4" sub floor and 1/4" cement backer board with 1/4" x 1/4" trowel of thinset equals this. If you are not sure, don't assume. Find a vent in the floor. Pull out the register vent and use a hand mirror to see the sub floor. Take a tape measure and measure its thickness.
The thickness is mainly for refinishing. Thicker wood can be refinished more times than thinner. If you are laying on a cement slab, you want to use a vapor barrier. Some flooring products have a barrier preinstalled on the undersideof the flooring.

The type of underlay you need will depend on the type of sub floor or floor you are putting the laminate on is made of. If the sub floor is made of concrete, you would want vapor barrier underlay. If the sub floor is made of wood a standard or premium underlay would used.
