It depends how the normal maps were made. Tangent Space normal maps can be reused on different models, while Object Space maps cannot. I would try Tangent Space first, and change if it looks wrong.

Tangent space normal maps are usually all blue, while object space normals are usually multi colored. Also be sure to set custom gamma to 1 for normal map
