The answer to this question is tricky. There are several different 'titles' that have been won since universities began competing in sports. There are NCAA titles which go back several decades (sorry, I do not know the history of the NCAA, but they have a website: ncaa.com). The NCAA gives out 'titles' to teams and to individuals. There have been other institutions before the NCAA that gave out 'titles' to universities. The only definitive answer that I know of, is based on NCAA team titles. UCLA has won 104 team titles with Stanford and USC in second and third with fifteen-to-twenty less team titles.
5 national titles.
The New York Yankees have the most titles with 27 world series titles
