I'm guessing that the question is how to edit these so, in general, I would suggest...
Straighten horizons.
Apply a slight S curve.
Push the blue saturation a bit.
Crop to the subject without centering, taking out anyone who's got part of their head sliced off by the frame.
Keep in mind the rule of thirds and how the composition works with shapes and lines.
Apply some artificial fill light to #7.
Sharpen till you just barely get halos, then back off on it until you don't.
For future shooting: Keep in mind the editing that would need to be done, then compensate at the time of shooting if you can to avoid having to do more work with them later.
Remember that photography is not just about the camera. It also involves the processing whether chemical or digital, in a darkroom or lightroom, and the display whether on a print or on a monitor. That's been true forever, and will remain true. Don't get lost on the idea that a "good" photo has no processing - read Asel Adams' trilogy: The Camera, The Negative and The Print - Nothing's changed exept for the transition to digital.
Also, I'd suggest keeping in mind that anyone who thinks you've posted too many shots doesn't have to participate in helping - nobody's twisting their arms.
