different shutter angles and their uses.

The term shutter angle refers to rotary shutters as used in cinematography. The frame rate of movie cameras is too fast to rely on a typical focal plane shutter, so rotating disk shutters are used instead. The angle between the the open and closed areas determines the shutter speed (without affecting the transport rate) The higher the angle the longer the exposure, the lower the angle the quicker the exposure (for rendering fast moving subjects without blur for example)
This does not affect still photography, expcept in the likes of swing lens panoramic cameras where the exposure time is defined by a choice of rgears and a variable width rotating slit to increase or decrease the exposure time.

I'm stumped. Unless you're trying to ask about shutter travel. Most shutter curtains travel horizontally. Some older Minolta and Leica cameras used a vertical travel shutter.
Or do you mean shutter speeds? Shutter speed determines how long the light is allowed to strike the film or sensor. It is dependent on the light available, on lens aperture and ISO. A fast shutter speed will stop action IF there is sufficient light and the lens is opened up enough to allow the fast shutter speed.
This is a hypothetical example. All settings are based on an ISO of 100 in bright light.
f2 @ 1/1000 second
f2.8 @ 1/500 second
f4 @ 1/250 second
f5.6 @ 1/125 second
f8 @ 1/60 second
f11 @ 1/30 second
f16 @ 1/15 second
f22 @ 1/8 second
All 8 of these examples would give exactly the same exposure to the film or sensor. All 8 would look identical as long as the camera was mounted on a tripod to avoid camera shake. A close examination would show a sharper image from f5.6 through f11 since lenses are designed for maximum image quality somewhere within that range.

A shutter shuts and opens at the speed set by the photographer. No other purpose. If you mean shutter speeds, it is to determine the amount of light entering the camera, the faster the shutter speed, the less light to enter.

are you referring to focal plane shutter... with its vertical/horizontal orientation? your question is quite vague.

I've had photography as a hobby for many years and I havn't a clue what you are on about!
