The second partidentifies the object or person in question (man, friend, tank). The first part tell us what kind of objecct or person it is, or what is purpose is (police,boy).

police               man                  policeman

One Word or two words ?

There are no clear rules about this so write the common compounds that you know well as one Word, and the others as two words.
