Can is an auxiliary verb, a modal auxiliary verb. We use can to:

talk about possibility and ability
make requests
ask for or give permission

Need - Depending on the sense, the verb need behaves sometimes like an auxiliary verb (such as can or may) and sometimes like a main verb (such as want or try). When used as a main verb, need agrees with its subject, takes to before the verb following it, and combines with do in questions, negations, and certain other constructions: He needs to go. Does he need to go so soon? He doesn’t need to go.

Must - The auxiliary verb must is used to express necessity, obligation, and probability: Plants must have water in order to live. Swimmers must take a shower before entering the pool. You must be joking. Unlike other auxiliaries like can and may, must has no past form like could or might: They insisted we must wait until tomorrow.
