At least some, if not all the leaves of Lilium canadense are arranged in whorls or partial whorls. #5's leaves are uniformly scattered. I don't think #5 is even a monocot. It's not Lilium canadense.
The white flowered ground cover type plant in the upper right of pic #5 might be Maianthemum canadense.
By the way kuklachica, you have a nice crop of poison ivy, too. Do be careful! Sorry I didn't notice it on the first pic.
