I ended up with these plants as extras a while back. They are doing ok, but I have no idea what they are. Could someone help with that?

Thanks!

1) The one with the spiky looking leaves.


2)The slender one I'm holding.


3) Obvious which one here.


4) the skinny, wispy one that looks kinda like cabomba.

#1 - Ludwigia arcuata (I'm pretty sure)
#2 - Don't know (But you're not talking about the crypt, right?)
#3 - Micranthemum umbrosum (I think)
#4 - Some type of Myrriophyllum

You guys are all looking at the wrong plants! LOL

1- Didiplis diandra
2- IDK? Looks vaguely like Najas, but I don't think that's it...
3- Lysimachia
4- either a Myrio or Proserpinaca palustris

#1 is not Didiplis, because the leaves are spiraling down the stem. That's the main distinction between Didiplis and L. arcuata (they are commonly confused for each other). Didiplis stems look like perfect X's, or plus signs, when you look down on a stem from the top.

But it's always hard to this from photos, instead of looking at the actual plant.

Well, to the OP, if the leaves on the stems of #1 are all perfectly aligned, where it looks like an X or a plus sign, then it is Didiplis diandra, for sure. If they seem to slowly rotate around the stem as each new node grows, then it is most likely L. arcuata.
