Alright, you are really pushing my Japanese comprehension, but with some reverse image searching, here is what I was able to dig up (needless to say links may be NSFW):

1. Top left - This is the cover of the September 2023 issue of an H-magazine called Muteki Renai S*Girl. I couldn’t figure out more info about the specific story (or stories) featured on the cover. (cdjapan source, publisher source)
2. Top right - I found this on mangadex. If you search for the author, Shinkai Yuyu, this work also shows up on some NSFW sites (though untranslated).
3. Bottom left - This is the cover of an H-magazine called Love Kiss! more, specifically volume 27. I couldn’t find more information about the specific story featured on the cover.
4. Bottom right - This is the cover of an H-magazine called Muteki Renai S*Girl Anette, specifically it is volume 62. Again, I couldn’t find any specifics for the story featured on the cover.
