They're called snowy or woolly aphids. They're hard to exterminate. I recommend you spend $10 or so, and buy a few thousand ladybugs (technically not a bug; but also called a "ladybird beetle" )
sounds like a fungus has got into the bush. You may fix it with fungicide, but maybe easier to tear it out, burn it, and plant something else
Could be mealy bugs...if you touch them, do they move? You can order ladybugs as a natural way to control them...
When did you prune them last and how old are they? From the little I can see it seems to be dead wood from lack of pruning. I can't see it well enough to give you a simple answer but if they haven't been pruned it's easy enough read up on how and when to prune them. If that's the problem.
It's powdery mildew. Its a fungal disease. I've had it on a few of my plants this year. Water the plant well under the foliage then mix 1 tablespoon of baking soda, 1/2 teaspoon of any liquid soap into a gallon of water. Then put in a sprayer. I also use a tablespoon of horticultural oil if the fungus is real heavy as that helps the mixture to stay on the leaves and plant stems. You have to turn leaves over and be sure to coat the top and bottom of the leaves. It helped my plants. I started watering the plants with my hose right at ground level keeping the water off the leaves and stems. That seems to help.
Maybe Lichen - because we used to see that growing in the forest behind my house - on trees that were damaged - but on some that were healthy? [namyco.org]
That is a very good explanation of the things I've seen on trees,scrubs and ground in the woods.
And the above photo (top right) looks much like the photo in the article of the small limb holding the hummingbird nest.

Posted by KateOahuI saw some pretty flowers on a walk today. I’d never seen a white Hibiscus before. And I do not know what the pink flowers are.
