It's just the body, i.e. the camera without the lens.

The lens is compatible because all Nikon SLR cameras are equipped with the Nikon F bayonet mount, as are all their Nikkor lenses of course. The battery is not compatible as far as I know.

I think you mean the "DEMO" So refurbished... Mostly cameras someone already bought.. and just brought back or a camera that was indeed in the shop. Digitec does not sell nikon refurbished. And it doesn't have 3Y warranty

Well, it doesn't say anything about a lens... and as we all know, you can't take photos without a lens... so... yes... they need... My recommendation: For portraits: Nikon AF-S 50mm, f/1.8G Wide angle, this is brilliant: Sigma 18-35mm, f/1.8 DC HSM ART, Nikon All in one but not exactly fast: Nikon AF-S DX VR 18-300mm 1:3.5 to 6.3G ED The 50mm should not be missing in any photo bag ;) and it is even cheaper: Nikon lens 50mm, f/1.8D AF Nikkor
