D1 has 11.7 to be exact, and very few programs in the country can and will offer that many.
D2 has 9
Division 3 has 0 but you will find more academic money at many D3 schools
JUCO has 24, but JUCO is broken down into 3 divisions (1, 2, and 3) 1 can cover everything, 2 can only cover tuition and books (no room) and 3 does not offer athletically related financial aid for athletes.
The NAIA can offer 12 baseball scholarships, although I also doubt many teams have that many available.
It all depends on the school.
