Just out of curiosity, does anyone know what happens should five positrons collide with a proton simultaneously?

Conservation of charge tells us there will be +6 after the encounter. Since the positrons are elementary particles, and the quarks in the proton are confined, I'm inclined to believe nothing much happens, unless the collision carries enough kinetic energy to generate new particles. Then I can't say either, except that they will have a charge of +6.
