The last part of your question worries me. Most Japanese nouns don't have plural forms and you need to get used to it.

警官　＝　警察官　＝ a policeman/policemen.

警察官 is a tad bit more formal than 警官 but the difference is minimal.

The informal word meaning a policeman is お巡（まわ）りさん.

警察 means the abstract concept "the police" and at the same time is used to mean the "police station" in informal speech.
