If the pictures are from the same origin (like if your camera was on a tripod) you could use astronomy software (look for image stacking) to denoise and attain a better image quality.
Linux
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

+1 from my side. I use Siril constantly to improve the signal-to-noise-ratio of my astro photos.
But I highly doubt that the photos OP described were shot in RAW and under the exact same conditions
I was thinking the same, smartphones would definitely do everything it can to make images sharp so it's probably not going to be easily stackable.
Still it feels like something should be there to combine the pictures to make better drawing, as there're softwares to generate 3D models from smartphone pictures.
OP still didn't describe in which aspect the images are bad.
Stacking (at least with astro software) only reduces noise, but even with stuff like focus stacking you can't turn a bad picture magically into a great one.
There's a reason why I always shoot in the shutter roll mode with my digital camera. When I have 5 pictures at once, there's always at least one that is sharp.
Playing safe is the number one rule of photography, hence why we always underexpose for example, since you can always rescue a too dark image, but if it's blown out white, you can't do anything.
Same with camera shake, focus, and so on. Even with all the AI shit and stuff, you just can't rescue some pictures.
I wrote a second comment in the section here with better instructions.

Especially since you need to plan that in advance and shoot under specific controlled conditions.

Another comment from my side: I think it would be best if you share some of the images, or at least describe what problems they have.
- Is the resolution not high enough? --> Try
Upscayl
- Are they blurry? --> Good luck. Rescuing blurry pictures, either because of motion blur or lack of focus, is the hardest/ almost impossible thing in photography. You could try some "AI" tools, depending on how sharp the image is, but they usually suck.
- Are they noisy? --> Maybe try
Topaz Denoise
(paid and proprietary) orGIMP
/Darktable
(FOSS, but not exactly as sophisticated or quick). Sadly, canceling out noise usually results in a "watercolor" look if overdone. - Or do yo just want to recover information? -> Increase contrast, sharpness and middle tones.
Either way, since you asked specifically in c/Linux (which I find a bit unfitting personally, better ask in c/Photography), I can recommend 3 Tools:
GIMP
of course, maybe with plugins, for general editing, andDarktable
for post-processing (color grading, sharpening, etc.) your images. The latter one works best with RAW images, which you probably don't have since you shot on a phone.Upscayl
for Pixel interpolation (usually doesn't increase sharpness, just the pixel count if yo want to crop more or print a poster at higher resolution).- And maybe Huggingface, which also offers quite some image processing AI stuff.
But as I said, please provide some pictures, or at least more information. Just saying "muh pics bad" is almost worthless for me.
AI upscaler ?
I would try hugin, manually do it in gimp, maayyybe an imagej plugin could do it, or whip up some octave or python code to do it. also, If you upload the photos somewhere im sure someone would be willing to take a crack at it.
Note, I think you will probably need to do lens calibration, alignment, then stacking.
CombineZP looks like it's just for this
