Yes you can. You must first paint over the old plaster with a product such as Eucoweld, which chemically adheres the new plaster to the old.

Break out the old plaster and plaster over the area to seal the plaster surface. It is best to lower water level in the pool first but there are patch materials that work under water.
No, you plaster or mud it first.
lath and mortar walls and ceilings have a greater flexibility than standard plaster. If you do plaster over it you firstly need to be very confident that the old mortar is sound and fully adhered to the lath. You would also have to seal the ceiling well to stop the water in the plaster from literally being sucked out of the plaster. Regarding tiles. If you are thing about ceramic tile then NO!. The weight of the tiles would pull the mortar from the lath with great ease. It is defiantly better to either plasterboard directly to the old ceiling and using dry wall screws NOT NAILS screw directly to the joist not the late you can then put a good scrim tale over the joints and plaster accordingly. The very best option however, is ...............drop the old ceiling, re-board and plaster
Asbestos used to be used in the plaster mix to help strengthen the plaster. So if you are ever renovating an old pool with plaster it is best to have it tested for Asbestos.
No
You can, but if the plaster is uneven at all, you should nail on 1x4 first to mount the drywall onto.
If you put plaster over a water balloon and freeze it, the water balloon will bulge out.

a fresco. (fresco is italian for "fresh" referring to the fresh plaster that has been applied to the wall. This is opposed to "fresco secco" which is painted over dry plaster)
The finish plaster is normally white all the way through. It sounds like you are dealing with a pool that has been replastered by the method of putting a "brown coat"/"scratch coat" (the gray plaster you noted) over the original finish plaster surface, and a new finish coat of white plaster on top of that. The scratch coat more like a thin concrete than plaster (doesn't have the white marble dust in it) and is used to get a better bond to the old surface.
