Most of these look like glass to me as well. Some things to look for: striations that came from winding of the glass to make the bead. These show very clearly on many of your beads on the outside. You can often see it clearly near the hole as well.
Also, the hole from a stone bead would be drilled, and if you hold it up to the light, you can generally see the difference, especially when a bead was drilled from two sides.
Air bubbles in the bead are a clear indication of glass.
Certain internal fractures on the other hand are more common for stone. There are two or three beads on your strand that show some signs of these fractures. So these might be stone, but difficult to tell from this image alone.
