Wildflowers are wonderful!
I recognize the first one right off the bat, it's Chicory-Cichorium intybus.
"Found this little thing too" is Heal All-Prunella vulgaris.
And the vaguely familiar one, I'm pretty sure it's Horse Nettle...
The yellow might be some kind of Buttercup, Ranunculus species. Not sure.
Yes on the Red Clover.
and the white one is probably White Clover-Trifolium repens.
