On the Echinodorus it looks like you have two species; the green one in the back is likely one of the grisebachii - sometime called amazon or bleheri. The one in front of it will eventually come to me also it might be in emersed form which means the current leaves would die and new leaves will grow in submersed form - i can't tell - as there are a few plants with submersed leaves similar to emersed - but i've seen that one recently so maybe if i sleep on it. Also you burying them a bit deep as they prefer the rhizome to be just breaking the surface - if the roots are short i'd leave them but in a few weeks try to raise them slightly.
I keep thinking it might be reni - it looks very similar to echinodorus reni. If it is reni then the leaves are in submersed form as the emersed leaves tend to be more green.
