From left to right you have Val but if it's twisted like it sort of looks it's probably Corkscrew val. The next two plant bunches are anacharis, which you need to take them out, cut the bottom inch off, then replant each stem individually with leaves almost but not quite touching the leaves of the stems around them. With two bundles you can fill in alot of area. On the far right appears to be water sprite and the one grass plant in the front looks like Cyperus Helferi.
