The red one is Alternanthera reineckii, the second one Rotala rotundifolia/indica. Might be the photo, but the Rotala looks a bit starved (not green). Alternanthera can be a bit difficult to figure out. I have it growing alright in my medium light tanks, but the lower leaves always turn a bit ratty, and I think snails are all over this plant, must be tasty. Try to plant a single stem somewhere rather than a big bush. Once it grows cut it about 2" from the bottom and wait for new growth. Or something.
