These filters are used to fix some common problems of photos. Each opened dialog will have only one slider except "Auto Contrast" and "Auto Red Eye Removal". They do not need to set anything. Move the slider to the right until the desired results are shown. Please note that the "Reduce Noise" filter is quite slow. You may apply it to a small part of the image first to see the results before applying it to the whole image.
