I like the last - the foggy water from the long exposure, the growth on the pier legs, the one light burst, the light from the side that we don't see, the reflection on the wet sand ...
I also quite like the first. The little lights on the sea (buoys?) irritated me at first, though. Had to look twice or three times (though that is a good thing, eh, if you look at a photo more carefully to understand it all???).
The textures in the second don't show as nicely as they do in the fourth. And the yacht (or whichever kind of boat that one is) in the third is more distracting than helping, I'm afraid.
I really like the first one. I may be wrong but it looks like a hdr on my screen, Just the way the colors bounce out at you
