Agree with these:

1. Sycamore
2. Don't know. more info required.
3. Oak. Petiole (stalk) looks relatively long, so bit hard to say which one.
4. Lime (most likely Common)
5. Beech. Looks like a weevil has mined this one. I can just make out a little brown line on the RHS of the leaf starting near the midrib and going to the edge.
6. Willow, relatively long-leaved, so most likely Crack.
