Here's a few:
Hemianthus micranthemoides
Rotala macrandra
Ludwigia arcuata - I'm sure you'll get better pics of this one.
Not entirely sure what this is, must be some type of Rotala
Not sure of this either, but this is the emersed of what I thought was aromatica, but isn't. Mine looks too scabby submerged to get a good pic of.
