Found a couple that don't match my guides. What are they?
The fruit or flowers of the first

I know this is an oak, just not sure what kind.

And it has this on it. They hang like fruit, but are hollow with a fuzzy tuft inside. The shell is papery and thin. You can crush it between your fingers with little effort.

Is it a fungus or bug?
Looks like what I call red oak up here.No idea the Latin name.
Stew, ya didn't include anything in the pics for scale, but I'm gonna guess that the leaves of the first one are rather small, and that it is Chinese Privet.
That oak leaf inspired me to go back and review WDH's very excellent series of threads on oak ID. It's tough to get a positive ID from just one side of one leaf, but Black Oak is a possibility.
The leaves on the first one are 2 to 3 inches long and 1 inch plus at the widest point. I'm pretty sure it is not privet. The pod has a dual green seed look when you open it up. The "seed" is in two identical pieces.
I'll look back at the black oak WDH posted about, but I'm really curious to know what the growth on it is. They were all over the branch I was looking at (about 20 or 30 of them). The back of the leaf was green and sort of shiny, almost identical to the front, maybe just a touch lighter.
I'm kinda thinking Carolina buckthorn for the first one rhamnus caroliniana
The last picture shows damage from a sawfly or tiny wasps. They sting a bud to cause a cynipid gall (http://www.entomology.umn.edu/cues/Web/171OakCynipidGalls.pdf) to form for their larva to develop inside. Tom has shown similar galls on his water oaks, his form fuzz and pokidots.
Thanks Swamp, the galls seem to match what I am seeing.
Just looking at the leaf, there are at least 3 possibilities on the oak.
black
shumard
scarlet
Given your location, scarlet seems unlikely, but the range maps show some disconnected populations from the primary range boundary that are close to you.
If you could find an acorn it would help. The shumard acorns are usually quite large and the cups separate easily from the nut. With black oak, the cup covers about 1/2 of the nut and does not easily separate from the nut.
Of course, it could be a hybrid as well.
If I were forced to wager on it I would go with black oak.
Radar, the top one appears to be an American snowbell (Styrax americanus), and I believe the oak is a black oak or a northern red oak. Look for fuzziness on the underside. Black oak has it, northern red oak does not.
The underside of the leaf was slick.
I would say the oak is shumard or scarlet, probably shumard since there are a lot of them in that area. Like LL said, the acorns will tell the difference. The acorn cup on shumard is saucer shaped and only clasps the base of the acorn. In scarlet, the cup covers half the nut.
Assuming you have access to the tree, there is also the bark scratch test shown here to rule out (or help confirm), black oak.

After sleeping on it a few nights, I have come around to DanG's black oak camp...
