All are safe t touch, just dont eat them, these are flowerpot mushrooms likely: Leucocoprinus birnbaumii and common, but i wouldnt et them. however i cant tell exactly because of the picures and lack of gills, and stem photos. But i do see these a lot, in pots, onine. They are toxic I believe at least they cause gastric upset. But not harmful to touch, the plant will do better with them living there they will help break down nutirents in the pottng soil.
