They are from the asteraceae family (I'm almost sure, though I could be wrong). Any help will be appreciated!
Welcome to the forums Meymar. Sorry I don't know the plant, but the newspaper background is not really that helpful .
I think some of these will be in Cretcher's Flores Silvestres de San Miguel de Allende Charco del Ingenio Botanical Garden (scroll down) Yes, they are all Asteraceae. I find this site to be helpful when identifying plants from Mexico: Una comunidad para naturalistas · NaturaLista The last one might be something close to this: Artemisia pycnocephala · NaturaLista (but I am not certain if that occurs in your area, no observations).
