Leaf Zone is useful but not as complete as Seachem Flourish comprehensive. I think the second plant looks like Java Fern. If it's leaves are coming out of a rhizome then that's what it is. The rhizome must not be buried under the gravel or the plant will die. Ferns grow best if you tie them loosely to a rock or wood. They don't like gravel.
