First pic, a lovely acer, just trim off any dead bits, the red ones tend to get a little scorched by the sun.
Third pic, big bush on the right is choisyia (mexican orange blossom), you can prune this when you like, I have one myself and its going strong. Has white scented flowers.
Fourth pic, the variegated plant under the acer is an euonymus, but I don't know which one.
