Welcome to Permies!
I have never been to Oklahoma but will give you my guesses…
The first one is definitely a mustard family member, probably of the genus Cardamine. Something in me wants to say “Cuckooflower”—Cardamine pratensis, a beautiful spring flower that covers hayfields here in mid spring. But as I am not an expert in Oklahoma flora I can’t get it down to species level.
Plant 3 is one I have seen before and eaten plenty. I think they’re whitetop mustard, but it’s not easy to confirm that until they’re blooming. I think Lepidium draba? They are good, quite hot.
Plant 4 is a thistle of some kind. I don’t know which species exactly. They sort of look like canada thistle but I am not confident enough to say for certain (not a thistle expert)
Plant 2, I have no idea.
It is lovely to see all of these spring weeds. Here in New England it just snowed today after the first week of warmth!
I hope this helps!
One can never be too kind to oneself or others.
