It's hard to tell with the pics you have uploaded... Not to mention most of those plants look like they're dying. How long have you had them? They're in terrible shape, sorry to say.
However, lemme see if I can help you out in trying to ID the ones that have a good clear shot that isn't on the brink of death!

Pic #1 I have no clue. Looks like it could be a some sort of sword plant.
Pic #2 looks like a val. To what sp? I have no clue. if it isn't a val, it's probably dwarf sag.
Pic #3 - Could be in really crappy shape... hygrophila polysperma (the plant on the left)
Pic #4 doesn't even look like a plant anymore. Might wanna toss that one out soon.
Pic #5 Brazilian pennywort (dying)
Pic #6 Rotala Nanjenshan
Pic #7 Rotala sp.? Ask your source what rotala sp. he/she keeps. It could be a stunted indica, colorata or rotundifolia. It's in poor shape no doubt and it looks stunted, due to it's small leaves.
Pic #8 Could be Java Moss, it's hard to tell what type of moss one has specifically unless it is tied onto something and is grown out some more.
Pic #9 Ludwigia sp. Again, check your source for a list of names. if it's not a ludwigia, it could be rotala macandra red. Although the leaf looks a tad too long for it to be rotala macandra.
Pic #10 Looks like a crypt melting. That plant should bounce back up after the melt, so don't throw that one away just yet.
Pic #10 The large mat under the water surface looks like marsilea sp. Minuta or quadrifolia perhaps? Or maybe even crenata. Those are the three more "commonly" found marsilea sp. The floaters, if that's the plant you're trying to take a picture of, is clearly duckweed.
Hope this helps!
Again, most of the plants you have above are in terrible, TERRIBLE shape. You may want to trash them soon, unless you are confident with your lighting/co2/nutrients dosing that you can bring em back to life.
Did these plants come in the mail in that shape? How long did it take to get to you? 2-3 days shouldn't have affected plants to that degree. A stunted rotala shows that it was never kept in proper conditions to begin with.
