Assuming a 1 stop increase between speeds, they would be: F5.6@125; F4@250; F2.8@500; F2@1000; F1.4@2000 Since most people are not likely to possess equipment capable of 1.4 and 1/2000, I would propose using an ND4 filter and a combination of F2.8@125 instead.
To use exposures, it is best to know what they are. Exposures are combinations of film speed, shutter speed, and aperture. To use them best, a photographer should use the results (via the camera's light meter) to see if the combinations will create the desired light in camera's sensor (digital) or film.
Shutter speed is how fast your shutter opens and closes to take a picture on your camera. Shutter speed also has a lot to do with exposure. The higher the shutter speed (1/2000 example) the less light.
Most cameras don't have a dedicated shutter speed longer than thirty seconds. If you wish to take exposures longer than that, use the bulb function ('B' on most cameras). Bulb allows the shutter to stay open as long as the shutter button is held down. Get a locking cable release, switch camera to bulb, and you can take any length exposure you want.
Night photography can be tricky. Generally, you have to allow for long exposures, during which the camera has to be perfectly still, so a tripod is important. These exposures can result in "noisy" (or grainy) photos. If you are interested in night photography, here are a few features to keep in mind: 1) Shutter speed. When an exposure has a longer shutter speed, it lets more light into the sensor, which allows for lower aperture and ISO settings. 2) ISO setting. When the camera is set at a higher ISO number, it requires less light for exposures. This means you can take your night photo with a faster shutter speed and still get the same result, but you generally do not want to do this. There should not be any movement within the frame, so you should use the base ISO setting so there is very minimal noise. Long exposures allow the shutter to be open longer to absorb the available light. Image stabilization features. This prevents movement during long exposures. Night scene mode, if it is available. This setting automatically provides low-light settings and doesn't require you to manually modify the settings. This option is good for beginners who are still learning about the different available exposure options. Noise reduction mode. Long exposures often allow noise - or grain - into your photo. Rather than use photo manipulation software to remove the noise, this setting automatically removes it for you.
All cameras have multiple shutter speeds and depending the mode your camera is (Manual, Auto, etc...) the camera will choose what shutter speed it thinks will be appropriate for the picture. And most cameras will also not tell you the shutter speed you used, while some will.
When you add a camera lens to a camera, it does not make the shutter go faster. If the camera has a manual way to adjust the shutter speed, that is how it changes.

the shutter speed is how fast the shutter can go eg. an dslr has a faster shutter speed than a digital camera the shutter is a part on the camera that opens and closes when it opens it draws the light from the object focused on and places it on the lcd screen of film giving you your pic

You can adjust the shutter speed of Canon EOS cameras so there isn't a set shutter speed.
The answer is Aperture. The Shutter Speed does not affect Flash output. You can prove this by setting up a camera with a flash in a room where you can control the lighting. Photograph an object in the room until you determine the best flash exposure...such as F 5.6, F 8, etc. Now that you know the F stop (aperture) that allows the proper amount of flash, turn off the room lights so that there is virtually no ambient light in the room. Leaving your camera set to the correct aperture (F stop), take different exposures by changing the shutter speed each time while not changing the aperture. You will see for yourself that the flash exposure is the same with each exposure even if you try one shutter speed at 1/60 and another at 1/2 second. The shutter speeds would only make a difference in the overall exposure if there was existing ambient light...then the exposure would become light or darker depending on the shutter speed. With a slower shutter speed the scene would be brighter as more ambient light was taken in, but the shutter speed did not affect the flash, only the ambient light.

The general rule from the film days was 1 over the focal length as the shutter speed. thus a 28mm lens the lowest handheld would be 1/30 and for a 400mm 1/500. shake reduction schemes may offer a stop or two benefit.
The shutter speed setting controls the picture exposure, or how dark or bright the picture will be. Wikipedia has some very good information on shutter speed and aperture.
