Can you turn right on red in all states?
Not exactly. As a general American driving rule, right on red is widely allowed after a full stop unless a sign or local rule says otherwise. But it is not something you should assume works identically everywhere.
Can you pass a police car on the highway?
Yes, if you do it lawfully. There is no general U.S. rule saying you must stay behind every police car forever. The problem is that many drivers speed, tailgate, or ignore Move Over laws when the cruiser is stopped or working a shoulder stop.
