Based upon a standard 60/40 blend of gravel and pumice aggregates in the concrete block mix
Volume of 1 inch block is 1 cubic inch Volume of 1/2 inch block is (1/2) x (1/2) x (1/2) = 1/8 cubic inch Therefore number of 1/2 inch blocks in 1 cubic inch block = 1/(1/8) = 8
9 inches x unknown x unknown
More information is needed EG what type of 12 inch blocks there are many(see link below). Also what way up are you using these blocks. http://www.boralbestblock.com/product-lines/masonry/standard-block/12-inch-block

It all depends on where you buy it.
The weight capacity of a concrete cinder block can vary depending on the block's size and design. On average, a standard 8-inch concrete cinder block can hold anywhere from 900 to 1,500 pounds vertically. It's always best to refer to the manufacturer's specifications for precise weight-bearing capabilities.
Unprotected steel is generally not recognized as having a fire resistance rating.

Absolutely, there is no limitation as to the width of a door as it relates to fire rating.
about 16 cinder blocks
The ones that I see are 2-3/8" thick and 6"x12" in size.
Calculate the exterior face area of he wall you want to build and the face area of the side of the cinder block (add about 1/2 inch to length and 12 inch to width for mortar thickness). Divide the wall area by the block area This is the number of blocks you require. This is how I figure out how many blocks you will need: First measure the length of walls for the blocks in feet. Second divide that number by 4 then multiply the total by 3. That will give you total blocks needed for one course of blocks.
a 2 in block is easier but a 1 inch block will teach the kicker to kick off the ground better like the pros
