It is less than a foot. 200 millimeters = 7.87 inches.
2.4 mm All kidding aside: the 3.5mm lens has a wider angle than the 6mm one. This means that in a picture, you will see a larger area with the 3.5mm lens, but with the 6mm lens you'd see more (sharper) detail.
Yes! Manual focussing is easy and that is a great lens.
You need to buy an adaptor. Make sure you specify exactly the type of lens and exactly the camera you want to attach it to. Don't forget that there will be a large increase in magnification, i.e. your 35mm lens will give more telephoto effect on a 16mm camera. It is unlikely that the automatic functions (aperture, focus) of the lens will be carried into the 16mm camera.
This describes the focal length range of the lens. It means that the lens can be set between 18mm (a wide angle which takes in a larger field of view) and 200mm (a telephoto, which creates a narrower field of view). ******* Note: the above is certainly true for 35mm format, but focal length is relative to the format. For 4x5 cameras, the equivalent "normal" focal length is around 200mm.
The "mm" marking represents the focal length of the lens as measured from the optical center of the lens to the film plane when the lens is focused at infinity. If the lens is a zoom, focal length is expressed as a range such as 28 - 80mm, which means it can be infinitely varied from one length to the other. Most zoom lenses accomplish this in part by varying the position of the optical center. The focal length or zoom range is typically indicated on the lens barrel and/or the area surrounding the front lens element. Lenses that accept accessory filters are almost never marked with a filter diameter or series size on the lens, though screw-in filters have the diameter indicated in millimeters on the filter rim. Since many lenses are stored with a filter in place, this might easily be mistaken for a part of the lens itself, particularly with screw-in filters, which normally sit flush with the front diameter of the lens barrel.

no!
It depends on the actual focal length. For a 35 mm format lens, 200 mm is about 4x magnification, to get 20x you'd need a 1000 mm lens. For smaller formats, such as 8 mm or a camcorder, find the focal length for normal view, then multiply by 20.
That number is the focal length of the camera's lens ... which focuses light from the scene to form an image on the 'film' or CCD inside the camera. The longer the focal length of the lens, the larger (nearer) the objects appear to be in the picture. (One radian of angle as seen by the lens ===> One focal length on the film.) On the cameras described in the question, the focal length is given as a range ... "from 18 to 200 mm", and "from 55 to 200 mm". Each of these is a "zoom" lens, whose focal length can be changed over the range, enabling the user to cause objects in the picture to appear somewhat nearer or farther away.

In standard film camera reference which is commonly used, a 50 mm lens equals a neutral value, or 1x magnification, so a 12x lens would be 600 mm.
