Neither are lilies. The first one is a Hymenocallis and the second one may be Lycoris though I am not real familiar with either of them. Hopefully someone else will pipe up.
Connie is correct on both accounts. I don't know my Hymenocallis either, but the Lycoris is definitely Lycoris squamigera, aka Naked Lady or Surprise lily.
