Oops sorry yes!! I forgot you'll probably be interested in species names..
@theyoungwaldschrat and @drzewobojczyni are right, first photo is Lamium purpureum (purple deadnettle), accompanied by less visible friends- Stellaria media (chickweed), Geranium pusillum, of course Taraxum officinale (dandelion) and Bellis perennis (daisy).. probably some plantain and dock in there somewhere too, and grass i will not even try to ID.
Second photo is coltsfoot
Third is.. uh. violet. Anybody knows violet identification? Not me.. I looked it up once and gave up. Yes, stinging nettle photocrashing definitely.
Second to last is a Mirabelle plum, Prunus cerasifera or some feral mix thereof.
Also, had no idea that butterfly has such a name in english. Brimstone, really?? In polish its name could be translated to "lemony summer-leaf", i think I prefer that name :D
