text: Some crimes merge (conspiracy to commit crime is not longer charged when you commit crime) and some dont' (attempt to commit and the actual crime can be charged as once. So you can be charged w/ all the non merging offenses, lower offenses, and higher offenses, as well as federal offenses. There is no limit to how many crimes you can be charged with. You could be charged w/ committing crimes in all 50 states (if they happened in the states)  plus federal crimes. People have been charged w/ hundred of offenses at once (child porn rings, etc)
