It looks like you have Mud Plantain...

That's a very nice plant to have. It's not aggressive here in Missouri, usually stays on the small side and in shallower waters if not on the muddy banks. I'd be thrilled to have it in my pond as I have tried to transplant some...it did not take. The smaller size of this plant makes it susceptible to being crowded out by taller plants.

I cannot say what the other photo is of. If could be the same thing, but I have no size reference or close-ups. It kinda looks like a type of Pond Weed, or maybe arrowhead. Too hard to tell in it's infant stage.
