A 15 inch tire of widths about 205 - 235.
235/75R15, I personally have 30x9.5r15 on mine.
that is fine, check for rubbing under wheel well.
Yes, as long as you have clearance for the front wheels to steer.
NO, this is not an acceptable swap. The 75 series tire will be 7.02% smaller is overall diameter. You should never go under or over 3%.
You can, of course, but it is not a recommended substitute. It is never acceptable to go over or under 3% of the OEM size. The 235/75-15 is 4.09% larger in overall diameter than the OEM tire. You can however switch to a 235/70-15 which is an almost perfect swap at only 0.92% larger. This would be the size you need to go to.
