The feathery looking plants on the left looks like a reasonably fast growing plant, though i don't know what it actually is
I can recognise the anubias and java fern - they look as though they are planted in the substrate? If they are, I need to warn you that the rhizome (the thick thing that the leaves grow out of) should not be buried or it will rot. These two plants are usually grown attached to decor for this reason. The thin roots, which grow out of the opposite side of the rhizome from the leaves, can go into the substrate, just not the rhizome.
If you can't find frogbit yet, try some stems of anacharis (elodea) and let them float. They won't look pretty but they help keep the neons safe and when you get some frogbit you can take a bit of anacharis out as the frogbit grows till it's all frogbit. And neons will like having plants over their heads as they, like most of the fish we buy, come from rivers with overhanging vegetation to screen them from bright overhead light.
If you do get the neons, test the water every day for ammonia and nitrite till you are sure they are staying at zero.
