The first has really nice colours but the top section needs cropping out to get rid of the dark area top left (a bridge maybe?)
The second is a nice image but it doesn't really have a focal point and the sky blow out doesn't help.
The third is also a nice image though I would crop top and right to get rid of the red berries and the highlighted leaf. I find both of these elements distracting to the main point of the photo which is the lovely light rays you have captured.
The fourth doesn't do a great deal for me personally. The horizon isn't straight and the leading line of the handrail is too far on the right hand side to be useful to the composition of the shot.
The fifth shot is a lovely sunset, however, I would either clone out the two vans at the bottom or crop it off completely leaving the horizon on the third
The last is quite nice too, only thing for me is thatb the colour of the water looks completely unnatural.
Nice selection overall which could be made much nicer with a few adjustments
