That first one is interesting. It’s in the brassica family so it’s safe in moderation but I couldn’t say which exactly. It almost looks like a domesticated plant, not a weed. Wintercress maybe?
The second one is a chicory, not sure which. I’ve got something similar growing in a weed patch now. I thought it was bristly ox tongue but it never got “bristly.” It’s safe but if you want to wait for it to produce a flower (yellow) to be absolutely sure, you can do that.
