From the upper left to right:

1. Cercis canadensis, definitely
2. Looks like Quercus prinus - chestnut oak to me.
3. May be Q. macrocarpa, but probably Q. alba.
4. Pretty sure its Robinia pseudoacacia
5. (middle leaf)need closer image ...maybe Housa dogwood, maybe a bunch of
things
6. Liriodendron tulipifera, definite
7. Quercus cocciea or Q. coccinea / velutina hybrid
8. probable Acer rubrum
