How can I define four different kinematic diffusivity in fluid and porous domain for the same AV? When I input the diffusivity value for one domain, other domain will automatically have the same value. Obviously the diffusivity is not the same inside each domain.

Check if constant domain physics is enabled and disable it. Other way is to define an expression and use there the logical inside() which returns true for the volume you are inspecting.
