The grey fruticose lichen is

The grey fruticose lichen is a Ramalina, but I can't see details clearly enough to be certain which. Ramalina siliquosa is the most frequent on coastal rocks but Ramalina cuspidata is very similar.

The orange lichen in your second photo looks more like Xanthoria aureola. In most reference books you will find it under its old name of Xanthoria ectaneoides.
