IMG_20211209_160419. - Underexposed, blurry and white balance should be warmer

IMG_20211209_16052 - same as above poorly composed with distracting elements in the background

Remaining images have the same issues. If the images had been technically acceptable, Adobe Moderators would most likely have rejected several for being too similar; they consider uploading a bunch of similars to be "spamming".

You see that the blacks are missing. You also have a white balance issue. I've never seen a camera taking pictures at ISO 506. This strongly looks like a phone camera. You will need to get much more light on your subject, to get the ISO to an acceptable range, or you need to increase the exposure time, which will introduce more camera shake if you do not use a tripod.

Hello,

Your white balance is an issue in these shots, apart from the focusing!

Along with the other reading material, you should also look at this:

Hi, the exposure is not optimal in the photos.  The white and black points need to be set such that the dynamic range of the photos is increased.  You want the range to extend all the way from black to white.  Also, the photos are a little dark.  These things can be fixed in a photo editing application.  

What can't be fixed is the shallow depth of field that causes only a small porition of the photos to be in sharp focus.  You can see this by looking at the rim of the bowl in the first photo.  Portions of it are in focus but others are not.  The f1.8 lens on your camera results in a very shallow depth of field at close distances.  That makes macro photography like this difficult.  With a DSLR or mirrorless camera you could use a smaller aperture (e.g. f5.6 - f8.0) to increase the depth of field and get more of the subject in sharp focus.  Best regards, John

160444: The same issues, more or less. I've taken a screenshot at 100% at the probably sharpest point. You can see that it is not exactly sharp. And there is a kind of strange double exposure (arrow):

I didn't really look into the other ones, but I agree with @Jill_C, you have pairs of very similar pictures.

In addition to what has been said, the cropping in the second photo is not good. The black corner at the edge of the table.
