The reddish plant is Ludwigia Repens. It looks like the shorter green ones in your 7th pic could be Bacopa Caroliniana. The small bushy one in your 4th pic looks like a Pogostemon not 100% on that though. The other stem look sorta like either narrow leaf ludwigia or some sort of Rotala. If you could get some better pics everybody could tell more from them. Good luck with your tank.
