No, it will burn, but needs very high heat to do it.
Concrete, tile, marble. granite, glass.
No, you may think you can, but the paper will just come off the sheetrock.
Noncombustible materials are those that will not ignite, burn, support combustion, or release flammable vapors when heated. While these materials cannot be ignited and will not support combustion, they may react to heat in a manner that could affect structural stability. As an example, unprotected steel is a noncombustible material, but it expands significantly when heated, which could either push a wall out or, if it is confined, twist and turn, with the possibility of structural members falling. In addition, at about 1,000°F (538°C), steel loses about fifty percent of its load-carrying capability.
It is put behind a fireplace as a precaution, like waterproof sheetrock in bathrooms.
Flame-retardant (I realize that's hyphenated),incombustible, fireproof, noncombustible, nonflammable...
yes
Concrete, tile, marble. granite, glass.
Calcium sulphate dihydrate is the primary material in drywall.
You cannot use sheetrock as flooring, period. If you meant on a wall, there is no reason you cannot put sheetrock over tiles. The question is why would you want to! Why not remove tiles and material behind, which is probably sheetrock, and then install new sheetrock. If it is an area prone to moisture you could use moisture resistant sheetrock. The job would look better and you would not lose the space by adding over existing material.
The core of the Sheetrock (gypsum) doesn't mold. But the paper that is on the front and back of the Sheetrock will mold. There are some types of Sheetrock that are green and are water resistant. And there is a new product that instead of using paper uses a fiberglass material, which makes it completely mold proof.
No.
yes
A barrier board is a variety of noncombustible board stock material of low thermal conductivity placed between two elements of a roof assembly.
Will not catch on fire.

Combustible fabric is material that can catch fire and burn when exposed to an ignition source, such as an open flame or heat. Examples include cotton, silk, and many synthetic fabrics. Noncombustible fabric, on the other hand, is material that does not readily catch fire or burn when exposed to these same sources of ignition. This type of fabric typically has a high resistance to flame and heat, making it safer in situations where fire risk is a concern. In summary, the key difference lies in their flammability properties, with combustible fabric being prone to ignition and burning, while noncombustible fabric is resistant to these risks.
Sheetrock, drywall or gypsum are insulators.
