Nominal 1/2" thick is standard.
In the US, the standard length for studs (the vertical boards that sustain a wall) is 92 5/8". In making a wall, the studs are fastened to 2 x 4 sill plates at the bottom, and a doubled top plate at the top. The top and bottom plates, all 2 x 4's (in most cases), are nominally 1.5" in thickness. That makes the total thickness of the plates 4 1/2 inches. The sill plate is attached to the floor, and the ceiling joists rest on the uppermost top plate. So, from floor to ceiling, in a framed structure, the distance is 92 5/8" plus 4 1/2 inches, giving a total of 97 1/8 inches. 96 inches is 8 feet, which is considered the standard distance from floor to ceiling. But, in framing, consideration is given to additional ceiling and flooring materials which will be used. Most bedrooms will have carpet, and gypsum board covers the ceiling. The gypsum board (sheetrock) is 1/2 inch thick, and carpet is usually 3/4 thick. Adding these together, you have 1-1/4 inches that will be subtracted from the original framing height, to give the finished height of a typical modern ceiling. Since the framing height is 8 feet and 1-1/8 inches, the typical height of a conventional residential home's ceiling will be 1/8" shy of eight feet, or seven feet, eleven and seven-eighths inches.

That depends upon location. Tiles can be installed on a gypsum board wall or ceiling. (But make sure that the tiles are well grouted; if moisure gets past the tile into the gypsum board, it will be damaged.) Floors require greater strength - but then, you wouldn't normally have a gypsum board floor, with or without tile.
The difference is the thickness and the type of paper covering the gypsum.
The answer depends onthe quality (including width and thickness) of the board, andwhere in the world you are trying to buy it.

You may expect an increase in noise attenuation of about 3dB for each doubling of the mass of your gypsum board. Using boards of different thickness on opposite faces of the wall will further increase the sound loss.
Sheetrock is a brand name for a brand of gypsum board, and by it's nature, it fire resistant (it is made of ground up gypsum rock, mixed with water, extruded in a ribbon). Check with a building supply dealer for fire code rated drywall- it will be the correct thickness.
No. Any washable paint can be used on a gypsum plaster board ceiling in a kitchen.If the ceiling has been painted previously, or is not new, before applying the paint, apply a coat or two of sealer. This will make sure that any residue from cooking grease will not make the paint peel off.Check the compatibility of the new coatings with the existing coatings. It may be necessary to etch prime. Talk to a knowledgeable person at a paint supply store for advice, or read the information on the paint can to check.
No, gypsum is not metallic.
