what do you call them in your language?

We don't name them, we just put it with the tootl box and hope we find it.

Whatever they’re going into + the word anchor Wall anchor, board anchor, screw anchor. I’ve heard a lot on it.

French: cheville expansive while most people would say just "cheville"

Bucha 🇵🇹

Generically they're almost always called Rawlplugs in the UK (like Hoover for vacuum cleaners) or sometimes just wallplugs but obviously they have numerous trade names.
