usage - "Do you have English?" and "Do you know English?"

Are these questions natural?

"Do you have English?"

"Do you know English?"

In this video: https://www.youtube.com/watch?v=PXhDlYREJyo at 0:26, the subtitles read "Do you have Irish". Is that structure used only in Ireland?

I also remember hearing an American person who is not uneducated say "Do you know English" to an Italian person.
