#1 is your best photo as a single image, due to subject matter and composition; compare it with the little boy who walks through the same or similar ice cave: he's cropped off at the feet, which is a shame, since the shot is of him walking...but his feet are missing and there is awkward top space apportioned above his head.
The old lighthouse: excessively contrasty, but a nice scene with the ladies there. The wall and van: not composed well, with the van awkwardly cropped off. Car seat and bokeh dots? Bokeh dots, even orange ones, are not enough to carry off this photo. B&W walkers? Tilted, not interesting; cityscape: camera shows buildings and tents, not much context.
These are photos that have meaning to you, but to me, they do not convey much of a viewpoint, or anything really interesting to look at. Most people would consider this to be vernacular photography, which has a place. You do have a sort of dispassionate, distant look to your photo style.
