Yes, for the (anti-)electrons. Antiprotons and neutrons should be able to annihilate as well, and vice versa. They are composite particles made of (anti) up and down quarks, so processes like antiproton (anti u anti u anti d) + neutron (udd) -> photons + pi- (anti u d) ( + pi0 maybe) could happen. The pions are short-lived particles called mesons, made of a quark and an antiquark.
