License

The repository doesn't have any license, what is the licensing for shaders that don't explicitly state anything?

I assume it's same as in RetroArch repository, but would be nice to make sure.

I doubt it, as I think these are ports of other shaders or algorithms, rather than RetroArch's original shaders, and they're used outside the scope of RetroArch too (e.g. by snes9x). I suppose you'd have to contact the authors of the originals to get licensing information, but it might be best to avoid (remove?) shaders without any license.
