First one is I think cabomba furcata, a difficult plant to keep going over long periods, but it might also be the red variety of myriophyllum tuberculatum, again with this plant not starving the lower leaves of light is crucial if you want to maintain it. I think it's probably myriophyllum to be honest.
The bottom ones are probably hygrophila guianesis, it grows in most conditions.
