My Yard of Weeds

After weeks of heavy rainfall, expect a yard full of unwanted weeds. But we have some blooms this time around. Anyone knows anything about these blooms?

This one has a number of cluster of flowers

See the bugs? Should I keep an eye on them?

Correct me if I'm wrong, these are Touch-Me-Not plants. It hurts to walk around them.

Saw some lantana blooms from a blog. Did I just strike a gold?

Someone came to clear the yard for us. But I'm keeping this one.
