Depends on the amount of mass that is added. In general it would probably either turn into a quark star, or if the mass is great enough a black hole.
It could eventually become a black hole.
no
it would explode
A linear accelerator works by having a magnet at the end of the accelerator. If the particle is neutral then it will not be attracted to the magnet and therefore nothing will happen, as in the case of a neutron.
It becomes Nitrogen-14
A neutron star already does contain a few stray protons and electrons, but that does not make it a new element. A true atomic nucleus is bound together by the strong nuclear force. A neutron star is held together by gravity and is composed of neutron degenerate matter.
A proton and a neutron added together would be Deuterium without an electron.

no
It would be Deuterium, also called Heavy Hydrogen.
That would be a collission between two neutron stars. Since many stars are actually double stars, this can happen now and then.

what would happen if you added silver ion to FeCl-4

In all probability - not that this scenario would happen - but the resulting combination of masses, would push the combined "stars" over the Chandrasekhar limit and a black hole would form.
Nothing would "happen" to them, but they would glow less brightly.
