UV filter:

UV filters are used in sunscreens to protect in photography to reduce haziness and fogginess created by UV light.

Those UV filters are suitable for both black and color films under bright sunshine because they could limit UV light from sunshine. The UV filter absorbs ultraviolet rays without changing the exposure. Also, the UV filter could be used to be lens protector and protect the valuable lens. It was because they could prevent the lens from being scratching and dust.
　

CPL filter:

What does CPL filter do?
It can darken blue skies turning them a deep, rich blue.
It also could remove reflections in water; therefore, you can see the detail in the water or river bottom during shooting a river scene.
It is also good with foliage, making leaves and less shiny.

It removes reflections from non-metallic surfaces:
Skies
Color Enhancement
Water and reflective surfaces
Light absorption

　

Star filter:
Star filters create points of light, like "stars," streaking outward from a central light source. This can make lighting within the scene take on a more glittering, glamorous appearance. This effect is produced by a series of thin lines etched into the flat optical surface of a clear filter. These lines act as cylindrical lenses, diffracting light points into long thin lines of light running perpendicular to the etched lines. Lines on the filter positioned horizontally produce vertically oriented star lines.
