Not sure about the others, though they don't look like any of the common aquatic plants we know here. Especially since the soil doesn't look too moist. Though, your location may change things. SE Asia has a lot of cool native aquatic plant sp. Try putting it in your tank, and see what happens. It's certainly worth a shot.
Great...i will try out the 2nd plant then.
