No. 2 somehow reminds me of a crustose, Catillaria chalybeia, but best wait for someone else who knows more what to look for; I'm only just starting out in likin' lichens  |

Hi again,
Usnea: you need to see whether or not its blackened at the base .....
1. Could well be Physcia leptalea - you get several different species on trees and twigs, and some of them show up on rocks as well

Jenny | Sorry Jenny, I have to disagree on this. The Physcia is P. tenella. When fertile it can have longer marginal cilia and look a lot like P. leptalea, but the photograph shows it is sorediate, which P. leptalea never is. Hypogymnia physodes and Parmelia sulcata also mixed up with the Physcia in the photograph, so it needs care to sort out what goes with what.
No. 2 is Lecidella elaeochroma - often an early coloniser of young trees in supermarket car-parks!
