Agree 1 Bush Vetch, Vicia sepium
2 Slender Trefoil, Trifolium micranthum
3 Look like seed heads of Whitlow Grass, Erophila verna + Epilobium shoot
4 Suspect hybrid Red x White Campion, Silene x hampeana
5 White Campion, Silene latifolia
1. Sea Daisy, Erigeron glaucus, garden escape, common by sea in South
2. Ivy-leaved Toadflax, Cymbalaria muralis, introduced in 1617! Common on walls.
3. Possibly Smooth Sow Thistle, Sonchus oleracea, try to take macro photos of bracts upper and lower leaves
