Does 5 AGC mean 5 amp?

No, "5 AGC" typically refers to a type of fuse, specifically a 5-amp AGC fuse. The "AGC" designation indicates a specific style and rating of the fuse, which is designed to protect electrical circuits by breaking the circuit if the current exceeds 5 amps. So, while "5 AGC" does imply a 5-amp rating, it specifically denotes a fuse rather than just the current itself.
