Yes
Yes. Nikon cameras have the distinct advantage over other cameras because they are backwards compatible with any Nikon lens. In short, any Nikon camera can mount any Nikon lens. The problem is how much of the lens capabilities are retained when used on a different camera. Depending on the lens' mounting system and the Nikon camera, the lens may or may not be able to autofocus or meter. Also, if you use an FX lens (from a film or D3/D700 camera) on a DX (digital DSLR) camera, the focal lengths will be different than on the film camera. More specifically, it will be 1.5 times the focal length of the film camera. (more zoomed in)

No. It's a single lens reflex digital camera.
The Nikon d2h camera has the ability to adapt to many different lenses. The lens that comes from the factory is the Nikon 70-200mm VR f/2.8 Digital Zoom lens.
No, this is a point & shoot camera and there is no lens mount. The lens is fixed on the camera and cannot be removed.
There is not a specific cleanser that you need to use on your sony camera lens. You can use any that is made to clean camera lens' As long as they say that they are camera lens safe and that is what they were made for then you can use it!
Sony Alpha SLT camera has a built-in image stabilization unlike canon or nikon. So any lenses will do as far as your photo concern. Personally for my a37, I use sony SAL 50mm f1.8 for portrait and 18-250mm tamron for all purpose use. These two lens are cheap enough to tempt you to buy.
