According to their Technical Data Sheet, 1 can will extrude a 3/8” bead approximately 134.0 ft under ideal conditions. So the cubic volume is 0.375" x 0.375" x (134' x 12)" = 226.125 cubic inches. 1 cubic foot = 1728 cubic inches. Therefore it would take about 7.6 cans to produce a cubic foot.

Can i apply this on a hot surface like car exhaust? Doesn't it catch fire?

I've used RTV silicone for minor muffler holes, good to 650 F. But it is flexible and doesn't stick to anything so you need to get it globbed onto both sides so it holds. Unfortunately the portion of a muffler that usually fails is where the pipe comes in (due to welding). JB Weld might work better there.

If this is injected between sheetrock walls, will it reduce sound transfer?

If you want to insulate the walls between rooms, it would be better to remove the sheetrock and use a spray foam insulation product, rather than a spray foam sealant. Bats of heavy rock wool might also be good sound insulation. A spray foam product expands for a minute or two and you risk popping the nails/screws holding the sheetrock in place if there is not enough room for it to expand fully. Trying to deaden the sound without removing the sheetrock would require punching lots of holes in the walls and spraying the foam through the holes, and then patching all of the holes and repainting. This will deaden the sound between rooms, but it will require a lot of cans to do it.
