So many questions! I'll try.
The juniper in the fire bucket - has the bucket got drainage holes? It must have, or the plant will get soggy and die.
The grey rosetted plant with the 'weird' extension is an echeveria and the extension is pribably coming up to flower bud. Pretty salmony orange flowers. It may be too late for the flowers to from, though.
The hydrangea - yes, you can trim off the flower heads, if they annoy you, but there is an argument that the old heads will protect the plant through the winter and you can cut them off in mid- to late March next year, which is normal for pruning that sort of hydrangea. Up close to the wall there it'll be alright to tidy it now.
Generally the planting is too dense and one or two of the plants will grow to large for the site, but that can be tackled next spring. The green brittle plant will spread as it has down, but if bis break offlike that it's easily kept small, isn't it?!
Question for you - Is it a warm spot, sunny?
