Second photo at least is a Common Broom (Cytisus scoparius). Sometimes they show more or less red wings in the wild but nurseries also cultivate this particular property, - for example, the one in your picture resembles a cultivar called "Andreanus".
# 1 Red resembles Lichnis coronaria, blue Myosotis sp. but it is not possible to say for sure based on the picture.
#2 is a red-flowered cultivar of Common Broom Cytisus scoparius 'Andreanus'. #3 might be a Wild Cherry, but the pic is too small to tell.
