Some plant IDs please

1. Was given this shrub by my dad, who is terrible with plant names! Yellow flowers in spring, red berries in the summer.



2. Saw thus in the GC today and my wife really liked it, I'm guessing Lambs Ear. It was in a display at the front so didn't have a label.



3. Flower and leaf from a plant tucked away in the corner of my dad's garden, my search has me believe it's an Acanthus Mollis?



4. This grows at the back entrance to my garden, a Japanese Barberry? But there seem to be lots of them. Need to figure out how to tame it!!



5. Climbing Hydrangea? Growing through, over and under my fence and over the top of my shed!! 


Thanks everyone.
