I don't recognize any except for the juniper.
I know that the juniper will leave you with bare wood if cut back past the green.
The one with needles?
I don't know.
Before cutting, or even reading about cutting... we probably should identify.
I'd be real tempted to get the sidewalk cleared... and worry about re-growth later...
But maybe someone else can offer a better solution.
I downloaded a book on pruning, but I don't know if it's what you need...
but, a free download?
Might help.
