The first one is a redbud tree, Cercis canadensis.
Number two - that is incredible, I've not seen anything like it. Where is this located (city,state)? Are the leaves really silver colored? Otherwise it reminds me a bit in structure of wax myrtle.
Number 3 is a wild Rubus, something like blackberry.
Four, I am not sure, what does the foliage look like?
Five looks like a Baptisia, as does #6.

I'm near Wichita Kansas
The leaves on #2 are a very unusual color. When I first saw it from afar, I thought is was a Russian Olive tree, but on closer inspection, I don't think so. I will get a close up picture and post it.
I will get a picture of the foliage of #4.

Russian Olive would have been my guess for #2

# 5 is either Carolina Lupine or the yellow Baptista (Baptisia sphaerocarpa). I'm guessing the Baptista, from the foliage.

The second one is a Chionanthus virginicus. Common Names: fringetree. You're very lucky from my stand point,I've wanted one for years.Here is a link I found for information on the Fringe Tree

I live on land that used to be farmed as well, and picture #4 looks remarkably like Fly Poison, Amanthium muscitoxicum. Of course, I live in WV so the species might be different. I am wondering if there was some sort of farm practice that promoted this plant.

Lady_6, I found another one nearby. If they have babies, I'll send you a few.

Enchanters, I have quite a few dozens of these scattered all over the property. And from what I've been told, the ground has never been plowed, i.e., it's always been pasture. So maybe the seeds are attracted to "cow patties"?

The second one is a Chionanthus virginicus.

No, it's not. Now that you posted a better picture, it is clearly a type of Elaeagnus.

And yeah, that other one does look like fly poison now that you show the foliage.
