Mostly vulgar stuff... 1 - Silybum marianum/Carduus marianus 2,4 - Cirsium vulgare 3 - Senecio vulgaris
Pic 2/4 is a species of Cirsium (or possibly the closely related genus Carduus), but not C. vulgare, which has larger individual flowerheads not produced in dense clusters like yours has. Getting it identified won't be easy, as southern Europe is a centre of diversity in these genera (~ 60 species of Cirsium, 40 of Carduus).
Thank you Michael I am trying to identify all of them and put them on file by photos. So i will need more help later. greetings from Southern Europe Albania
