Hypothesis:- A tentative explanation for an observation that can be tested by further investigation.
Theory:- A statement or principle devised to explain a group of facts especially one that has been repeatedly tested.
Law:- A statement describing a relationship observed to be invariable between or among phenomena for all cases in which the specified conditions are met: eg- the law of gravity.
Theorem:- (In this sense) A mathematical proposition that has been or is to be proved on the basis of explicit assumptions.

To know how they differ, first know how they are similar: They are all "Explanations".
Now, the difference:
Hypothesis - Tentative Explanation.
Theory - Verifiable Explanation.
Theorem - Demonstrable Explanation.
Law - Definite Explanation.
That, in a nutshell, is that. Now, don't ask me what's the difference between Verifiable and Demonstrable! :)

Verifiable will mean that you can show that there is evidence for it. Demonstrable means that you can do it again to show people the evidence, and that they can do it too. A law in science is something that seems to work in practice, seems to work in theory, and no-one has yet managed to disprove it or come up with something better (but you can bet your bottom dollar that someone somewhere IS trying!).
