I'd need a better picture the first could be Bristly Ox Tongue. Do some of the leaves have a bumpy surface? And if you grab a leaf, does it feel a little bristly (not ouchy)? Does it stick to your jeans or shirt?
This plant is everywhere in my area right now. Sometimes it's knee high and sometimes it is so low it hugs the ground. Eventually it will produce a yellow flower.
Anyway, if that's what it is, it's safe and a good food. My Russian took a little while to get used to it but she likes it now.
