Second plant is definitely Green Alkanet, Pentaglottis sempervirens. A very invasive thug but popular with a range of generalist pollinators & will support Scarlet Tiger Moth larvae & Forget-me-not Shieldbug amongst other invertebrates.Larger plant is 'Love in the Mist' Garden escapee, and the smaller some form of Mysotis/Forget-me-not.
Second picture I think might be Green Alkanet, orginally a garden plant but long established in the wild.
Agree with 1First looks like a bellflower maybe Campanula trachelium
Second is a Silene (Campion)
Third might be Viscaria (Sticky catch fly)
Fourth probably Mullein
