Are this glyphs of the "Private Use Area" correct?

What do you mean by "correct"?

These look like nerdfont extended glyphs.

Because I don't see them on https://www.compart.com/en/unicode/U+EAB0.
Writing here  we only see a square glyph. So I wonder why github doesn't recognize?

I think private use area means it is reserved range that will not be filled with official unicode symbols. That lets custom font writers (such as nerd fonts) create and assign whatever symbols they want to those ranges.
