Nickel is a metal atom, and metals form cations (+ve ions), therefore oxidation state of nickel must increase in the reaction from 0 to +X. Nickel is oxidised in the reaction, reducing silver ions therefore yes, nickel is the reducing agent.

Anything that gets oxidize is a reducing agent. Silver ions, the oxidizing agent, would gain an electron so they would be reduced, going from an oxidation state of +1 to zero. Nickle atoms become nickle ions by losing electrons, so they are oxidized and their oxidation number would go from zero to +2
Remember: OIL RIG
Oxidation Is Loss of electrons. The oxidation number becomes more positive.
Reduction Is Gain of electrons. The oxidation number becomes more negative.
If something is oxidized it is the reducting agent.
If something is reduced it is the oxidizing agent.
