If you want to show structures on the moon, you have to take photos of it with daylight settings, as the moon is very bright. Your camera will "shout" "too dark" at you, but just ignore those "shouts", as the camera mostly sees the dark sky around it and therefore "thinks" "it is dark, I need a long exposure". If, however (like it may have been the case when you saw the moon and these clouds) you primarily want to show the light the clouds take up by the light of the moon, you might wish to let go of all the structures (craters and such) and overexpose the moon some to rightly expose for the clouds. That would ask for some longer shutter speeds, of course. So quite much depends on what you want to achieve with your photo. In all of these, though, I feel you failed in both as there must have been a strong wind going up where the clouds were so they dashed past the moon and you only get stripes because of your long shutter speeds. While - I must admit that - THAT effect might also be a desired one... but these don't look like you meant to show the motion... Try and error is so easily done with digital photography. You can do so many test photos with many different settings, and you will learn which setting works best for what purpose.
