One of the great things about digital photography is that you can shoot and see the fruits of your work very quickly, learn from it and try again. In days of yore with film you could wait weeks to have your shots developed (unless doing it yourself) and invariably by that time had forgotten your settings or what you were trying to do
Only advice I would give you on these first shots Jill is if hand holding use an aperture that will give you a higher shutter speed to ensure the possibility of camera shake is negated, assuming of course you were shooting hand held.
3. ISO800 F/32 1/25 44mm - Even with the ISO wound up a shutter speed of 1/25 is very slow if hand held; you obviously were not on the 'pop' the night before If a tripod was being used ignore my comments
Best way to learn is as you are doing experiment, shoot, and learn from the result.
