There is this guy in my city who is selling shrimps that he breeds, about a month ago I bought 20 RCS's from him with the idea to start a 25L shrimp aquarium, when I bought the RCS's I saw that he had a lot of cool plants too so I bought a few floating plants too.
They are multiplying and growing at a very rapid rate, which I don't mind at all since they cut a bit the light from the aquarium and prevent algae development, but I would just like to know what they are called so I can look up a bit of information on them... There are two species one smaller (grows between 0.5-1cm and one bigger, grows between 6-7cm it also has "hairy" leaves and really long, fuzzy roots), the first photo is top the second is bottom view.
The third photo is of a plant that I also got from this guy, I know its a pretty common plant but I like how it looks and also grows very fast, I don't know its name
Any help with identification would be greatly appreciated

The common names for your floaters are duckweed and water lettuce (I'm pretty sure it's water lettuce).
The stem is a Limnophila species. I think sessiliflora but not too sure.

Pretty sure the above info is correct.
The last plant - the stem, is likely Limnophila, but it's possible it's a variety of Cabomba instead.

No question second is a Limnophila. What species is impossible to tell. You'd need flowers for that.

Thank you all for the ID

I think your floater is Dwarf Water Lettuce (Pistia stratioes)

No such thing, the common name is still Water lettuce. They are Pistia stratiotes as you correctly named, except what people label as 'dwarf' is just a different way water lettuce grows due to the environments of our aquariums (they're small).
