Must expresses obligation and a strong necessity, it is followed by a verb without “to”.

Have to, is an equivalent of Must but not as strong.

Students have to do their homework.

Must not or Mustn’t (a contraction) expresses prohibition, something forbidden to do.

Examples :

You mustn’t smoke in a cinema.

Needn’t or don’t/doesn’t have to express the lack of necessity, something which is not necessary.

Examples :

Must also expresses a logical conclusion.

Examples :
