Can someone explain what are the different lens and filters?
and maybe some sample images of what different lens and filters can produce?

A lens is a piece of glass (or plastic or something like that) which directs light to a certain position. A good example of a lens is your eye glasses (assuming you wear a pair of glasses). Obviously glasses cames in different "strengths" because different eyes have different needs.

Filters, as the name suggest, are just that - filters. They filter out different kinds of light rays depending on what they are make for. For example, ultra-violet filters are used to filter out UV rays. Red filters filter out blue rays and allow red rays to pass through. But filters do not have light converging abilities.
