Most often +2, but sometimes +3 in nickel compounds. The oxidation number of nickel in pure nickel is 0, as in all pure elements.

Nickel mostly forms the +2 ions with several anions so its valency is +2. So the valency of nickel is 2

Same as the number of protons- 28. Unless its an ion, in which case it will probably have 26, although 27-24 are all possibe, albeit less likely.The number of neutrons is 38.
