Campanula and some flowers for ID

[KeenTeen17]

1) This was growing on an old wall.

2) Is this Broad Leaved Everlasting Pea?

3) Is this 3 Nerved Sandwort or Upright Chickweed, I was sure it was but now I think its the 3 Nerved .

4) Sea Mouse Ear?

5) Weld or Mignonette?

6) Sticky Storksbill?

3) looks more like the 3-nerved sandwort - habit isn't right for upright chickweed
4) sea mouse-ear - glandular hairy, well notched petals, upper bracts all green
5) definitely weld. Wild mignonette has entirely different leaves
6) I'm sure this is the common storksbill. (I don't like the English name 'sticky storksbill' because the common storksbill is also sticky! Perhaps someone can suggest a new English name for Erodium lebelii!)

The Campanula could be Adria Bellflower, Campanula portenshlagiana, which grows on my own garden wall. It's native to the former Yugoslavia.
