They convert in to two photons
An anti-matter proton (or simply an "anti-proton") differs in charge, and thus spin as well.
An "anti-proton".
If you are asking whether the nucleus' mass would increase, the answer is no. Beta decay involves emission of an electron from the nucleus. This happens when a neutron converts to a proton, an electron, and an anti-neutrino. A neutron is heavier than a proton, and the anti-neutrino carries away some energy with it, so the mass of the nucleus decreases.

An anti-proton is a particle, the opposite of a proton. In theory every particle has an anti-particle and if a particle collides with it's anti-particle they wll both be destroyed and a large amount of energy will be released. Anti-protons were first made in a laboratory in 1955, and are routinely made in high energy particle accelerators today.
An electron? No, the Anti-proton is the negative charged opposite of the positively charged Proton.
There are several of them, including the proton and the anti-electron.
A proton has a mass slightly less than that of a neutron. A neutron is slightly more massive due to the extra mass of an additional electron.
A nucleon means either a proton or a neutron, yes. However it is conceivable that the word will be extended to mean anything forming the nucleus of an atom. For example researchers in CERN have managed to produce anti-hydrogen. The nucleus of such an atom would be an anti-proton. It might be reasonable to call that one a nucleon as well.
