Yes. You are right. Bindweed lobes are higher on the leaves.
7 -- Saint Johnswort? Unless this photo is an extreme close up of only one flower on a spike. (Or could be St. Andrew's cross -- they look very much alike. Hypericum spp.)
Doesn't St. Johnswort have fewer petals? St. Andrew's even has fewer petals.
9 -- Joe Pyeweed (Eupatorium purpureum) A great butterfly plant.
Looks like Knapweed of some sort. The coloring is more like Ironweed, but the leaves are wrong, and I never seen Joe Pye Weed with multiple leaflets, but I may be wrong. Also flowers for Joe Pye weed are not as generally as deep purple as those shown.
