how many were houses i can build in an acre of land
A 5,000 sq. ft. lot would probably be an optimal minimum, but you'd also have to consider roads. An acre has about 43,000 sq. ft. (about the size of a football field), so theoretically 7 or 8 houses could be built on an acre, but you'd have to consider driveways, unless the lot was narrow and along road access.
