As of the end of the 2009-10 season, the answer would be, 8.
In division 1 NCAA football there is no official national champion, however the University of Alabama has won 8 AP poll national championships. The years were 1961, 1964, 1965, 1973, 1978, 1979, 1992, and 2010 (the 2010 was for the 2009 season, but won in 2010).
The school, however, claims 1925, 1926, 1930, 1934, and 1941 as national championship years because they were named NC's by polls such as BR, BS, CFRA, HAF, HS, NCF, PS, and others that are often not recognized. Alabama is also tied with Noter Dame for most NCs with 8. Noter Dame and USC also claim 11 NCs for reasons like alabama. Oklahoma claims 7 even though they have been named NCs 17 times by other polls.
If we talk National Titles, it would depend on who you talk to. The School claims 13 national titles, however, the College Football Data Warehouse (CFDW) only record 12 titles. This is because in 1941, there were 3-teams up for the National Title (Alabama at 9-2, Minnesota at 8-0 and Texas at 8-1-1). Back in 1941 there were 14 selctors that picked the National Champion. The voting went as follows;
11 selectors for Minnesota,
2 selectors for Texas and
1 selector for Alabama
The AP selector picked Minnesota, however, since 1 selector chose Alabama the school claimes the national title. The CFDW has Minnesota listed as the official Champion of 1941.

Mississippi State University has not won any NCAA football national championships. The closest they came was in the 2014 season when they finished the regular season ranked No. 1 in the College Football Playoff rankings, but they did not secure a national title. The program has a storied history and has achieved significant success, but a national championship has eluded them.
