I like the idea of framing with the branches in #4 but it borders on maybe too many branches. In the first three I'd think about the framing, I think there are too many parts of things in the pictures (part of a tree trunk cut off etc.), and the one of the boy on the swing would be fun but the head's too much out of the frame and makes him look cut off, but I like the footprints in the snow.
Try thinking about what you see in your viewfinder before pressing the shutter button, whether or not everything in the frame is what you want in your picture. I agree #5 is the best one, it seems to show what you want the viewer to see. These work nicely in B&W.
edit - The thread titles make me think you're trying out Morse code! lol
