I'm not an asbestos expert, and don't suggest working with asbestos
yourself. However, if these tiles are 'safe' or you can be 'safe' I
recommend a hot air gun. You might find the tiles come up so easy,
you might remove them all.

Instead of a hot air gun, I suggest the safer venue of placing a towel
on the target tile and then applying a hot iron to the towel for a few
seconds, just as if you're ironing a shirt. The tiles peel right off.
