Whats wrong with these pictures? I don't get it!
HELP PLEASE! ...
Nor do we, because we can't examine your pictures at high detail to see the technical problems, which is what Adobe's reviewers will do. Please post 1-3 (no more) original files - exactly as you uploaded them, not re-edited in any way.
Thumbnails don't tell us anything.
That said, vacation snapshots might be OK for social media but they are not Stock worthy.
Adobe Stock customers expect the highest visual and technical quality for use in commercial projects -- i.e. posters, product packaging, print and digital ads, videos, movies, t-shirts, coffee mugs, calendars, etc... Read these links.
And I support @ricky336's claim, that the overall value of these pictures is not good enough for stock. So even if they were technically correct, they would get refused, probably with aesthetics and commercial appeal.
If you are new to stock, you should consider these resources: https://helpx.adobe.com/stock/contributor/tutorials.html

Sorry, these photos aren't really any good for stock photos. The overall quality isn't good; problems with composition, exposure etc. They are fine as holiday shots, but how could these be used commercially? You have to think about that!
