All of them can be reducing agents, even the hydrogen peroxide, believe it or not. Usually hydrogen peroxide is a powerful oxidizing agent, but there are some reactions (radical reactions) in which it will act as a reducing agent. All of the other metals are reducing agents...especially potassium (K), it can reduce just about anything!
