The second, third, and fourth plants are already ID'd, so I'll suggest one for the sword plant. Going by leaf shape, I'd say it's Echinodorus bleheri. If this is right, then you can expect it to reach 20 inches in height, with 20-30 leaves. It's easy to grow, pretty much the most common sword being sold through retail sources. Don't be shy about trimming off leaves from the bottom as it grows or it'll shade the light from everything else you're trying to grow. Propagate by cutting the rhizome. Light-Moderate lighting is fine. Most swords need a little fertilizer spike at the roots now and then to sustain all that foliage.
Your plants look great. Hope you'll take photos to show us how well they're doing.
