I'll cut/paste Silversurfer's answers here, and provide slight upgrades...
1. Styrax japonica - Japanese Styrax
2. Asteraceae member; sorry, I'm not a herbaceous guy
3. Asimina triloba - Pawpaw
4. Abelia sp. - those pink flowers, so few, and their size make me think it is something other than A. x grandiflora in Charlotte NC
5. Berberis julianae - Wintergreen Barberry
6. Euphorbia sp. - no additional help here, either.
