Could you please let us know where did you get this Font from?
This font seems to be not only "experimental" as written in the readme file, but also a Beta version. The one y in your screenshot is assigned to the category style variations (or similar), the others not.
In InDesign you can get the different glyphs - Photoshop doesn't like them. Both apps are newest versions. You can't transfer them with copy & paste. Perhaps Photoshop can't see them - but I don't know why.
