I would rule out any sword, as imo they are heavy root feeders and can quickly outgrow a 20gal. That is, unless you are very persistent with trimmings, in which case they will bend to your will and not grow above the water line.
The umbrella plant could be anything, the PlantGuide says its either a pond plant, or its similar to hairgrass. That's a big difference, so use your best judgement there.
Java fern for the win.
Anacharis is an excellent low-light, fast-grower IF you don't use Flourish Excel. It has been known to melt if you dose your tank with Excel, creating a nice soup. You might have different results though, this is just an FYI.
Tropical fern could be anything. Do a search on that Plant Guide for fern and you'll see what I mean. Try to identify it by the pictures. I don't want to jump the gun, but it should be a relatively fast grower, similar to java fern.
I've never particularly liked the way the big stores stock plants as they're generally not labelled well or at all, which makes doing what you're doing now nearly impossible. If at all possible, call around to some LFS' to see if they sell plants, then repeat the whole name->identify scheme.
Hope this helps, keep up the search!
