Grasslike plant looks like jungle vallisneria. Fern looks like a bolbitis species. Most mosses would work for that moss-look you're going for. Of course, I could be dead wrong on all my plant IDs.
I have no experience with bolbitis or whatever that is, but vals and mosses are not extremely particular when it comes to lighting.
