On the maple. Are those wilted leaves? They look an awful lot like bagworms

Are you saying they are all the same insect? If so i vote for Japanese beetle--except last one which is some kind of scale.

No, I'm not implying that it is the same thing causing everything but they are all in the same bed.

No, the healthy leaves are not wilted

Those are cocoon looking things hanging on the Japanese Maple.
They are made up of parts of the leaves and stem

I'd say bagworms. They will cleanup hawthorne down here. We came across lorepetalum that they had worked over along side hawthorne within the same landscape.

Red Maple--Wow! I have never seen Bagworms on these trees before!!! That is what they are.!!
Hawethorne is beetle and caterpillar damage.......what kind is a mystery!
Knock out Rose is definately beetle damage. Down here that rose variety is fairly safe from most insect attack and fungus.

I cannot identify the other plant without more of a view, but the spots look like beetle larvae or possible scale crawlers or beetle larvae.

Try to apply Malathion for the sucking and chewing insects like the beetles. The odor will help keep them off. If the customer don't want the smell, then apply some Disulfoton crystals around the rootzones and water it in thoroughly. It will have an odor for a few days. Dipel dust will help! Seven dust will help!
For the bagworms, Bifenethrin and spray in the evening or the early morning when these worms are feeding.
