7. is definitely not yarrow, it's an umbelliferae. Possibly hemlock but the leaves in the third picture don't look right to me. Are you sure that picture is the same plant as the first two? I've seen hemlock and wild carrot growing together and it can be easy to confuse two different umbelliferae like that (but no you won't get poisoned by touching it unless you have a touch allergy to that plant. Some umbelliferae are intense though, so do a bit of research). As mentioned the dark splotches on the stem, and an unpleasant smell when crushing the stems will help ID it if it's hemlock. If it doesn't have those, you can look at keys like smell, hairs or absence of hairs, what the root is like etc. Umbelliferae is a big family though.
