The one in the lower picture is java fern (microsorum pteropus). It's an easy plant to keep that doesn't really require any attention except that you avoid burying the rhizome in the substrate.
In the upper picture, the reddish plant in the backround is Alternanthera reineckii. It likes good light, but survives with less (just doesn't look as good). Generous amounts of nutrients (iron in particular) make it a deeper color.
The striped plant is Dracaena, a non-aquatic plant that will eventually (in a matter of months) die, unless you remove it from the tank and into a flower pot (or place it high enough that the upper leaves can grow emersed from the tank). I don't recognize the plant on its right side, but it doesn't look aquatic either.
