What nossie said, some of these could really use levels and contrast - #1 needs some contrast, definitely.
#3 with the moon would've been nicer if there was more detail in the moon - it's looks like a bright white blob without the details.
I would say #5 is your most interesting. You have the leading line of the road going for you composition wise. However, I think that this photo would look good with a vertical crop around the S curve of the road. Try it and see what you think.
