I call on your expertise.
Could you tell me why my photos are not accepted?
Thanks a lot
2159: besides the sharpness, you have a problem with the white balance (get it colder) and a strange histogram, suggesting missing contrast. It may be possible to correct this image, all depends on adding just the correct dose of sharpening.
0165: in addition to what @Test Screen Name says, you also have a white balance issue. Here the image is too cold. However, the sharpness is not recoverable.
9917: this is an interesting picture, it is, however, underexposed and slightly blurry, and the blur seems to result from camera shake. You should have shot more open (lower f-value) for a faster exposure time. I don't think that the image can be recovered.

Due to the fact that all of them a not in sharp focus, customers won't be able to use them, so they won't sell and therefore Adobe won't accept them.
They can't be rescued. ☹️
Have a look at the Adobe Stock tutorials:
Have a read of this from Adobe about how to create better photos:
This is out of focus and color fringing is visible on the abdomen.
The bird is totally out of focus. You used too much of a slow shutter speed to capture this one.
The frog also is not in focus and there is also a white balance issue.
In addition to the link you got you may also find tips to improve your file here.
#2 Focus (or motion blur). Look how blurred the goose is at 100%
These are difficult shots but Adobe's customers make no allowance and would want a refund for this picture. They expect "national geographic" quality in every shot, no matter how rare or difficult.
All 3 are too blurry, which is easily detectable when you zoom in between 100-200%.
It's clear enough without pushing the analysis, your photos are blurry. Imagine that you are a customer and you need a photo of a frog for an advertisement for example. Be fair with yourself objective self-criticism is important to evolve. Imagine for a second your image of Frog on a wall poster or on a bus for example. If it can help you here is an example. I'm not saying that this photo is perfect, but it still gives you an idea in which direction you should go. Hang in there !!!
