Probably you will need to buy the whole set, I doubt you will be able to find just a few keycaps that will match your set.
Google “This is plastic” set, I think they also have similar color scheme

Yes. Or something more specific, like r/clay or ResinCasting.
Edit: But I might need to search for them before making this kind of suggestion

Would be nice to have a community about diy and crafts

Thank you)

And I definitely had never stabbed myself with a chainsaw on this keycap
