I would get advice from a professional. I suspect that the cement backed board (plaster board?) would crack and turn to powder under the flexing as people walk across the floor.
can you mix ceramic and porcelain tile on a bathroom floor
It will depend greatly on the thickness & install method, however a standard unit of measure would be .020 for 1/4" thick tiles which is almost the same value as Concrete at .100 for 1" thickness
Most ceramic tiles are laid over a wooden subfloor, except for those on the ground floor of a house with a slab foundation. I will add to the answer above by saying that you will need to use a polymer-modified thinset morter when installing ceramic tiles over wood. Most tile-setting morters available today are "modified", but check to be sure, because regular morters are designed to be used over concrete and will not adhere properly to wood. Also, if the floor area is large and there is more than a tiny bit of flex in the floor, you might end up with cracked tiles, especially if you or your family or guests are heavy. To avoid this, it might be necessary to build up the thickness of the floor by adding another layer of 3/4" plywood, or by using the older method of wire mesh and concrete over the existing wood (in which case you would not need a modified morter).

Ceramic tiles come in various thickness, a 8 x 12 could be 1/8 if it's a wall tile or as much as 3/8 if a floor tile.

Yes, but you should be careful when polishing ceramic tile floors because they can become slippery. You can buy a floor polisher from sites like Amazon or rent them from Lowe's or The Home Depot.

You apply ceramic sealer, available at your tile store.
Ceramic. Ceramic.
You would slide across the floor in socks, not shoes.
yes
No, ceramic is a glazed product. It has no pores and would not allow the varnish to adhere the the surface.
