I agree, not one of them look like San Pedro. San Pedro typically has thicker ribs, and different shaped spines.
Cacti are generally quite variable in mescaline content, so you'd be lucky if that one you said was a peyote was very active. It doesn't look like any peyote I've ever seen.
You may want to look up and see if you can have peyote shipped to you from Holland. I don't know your laws concerning this, so be sure to check. Seeds for San Pedro, Peruvian Torch, Achuma, or Loph. Williamsii (peyote) may be an option for you, too.
Be an adult only when necessary.
