ID-1 & 10 - are the same I think. I'm not sure what these plants with dark purple underleaves are, but I've also bought them at one stage and they quickly died, so I assumed they were non-aquatic plants. Maybe they just needed massive light or something else I couldn't give them.
ID-2 - Valisneria
ID-3 - non-aquatic plant which will eventually drown
ID-4 - maybe Echinodorus Bleheri
ID-5 - Lobelia Cardinalis
ID-6 - looks remarkably like hair algae, whatever it is!
ID-7 - Microsorium Pteropus
ID-8 - looks like Sunset Hygrophyllia, not sure
ID-9 - some type of Cryptocoryne
