Echinopsis pachanoi should have up to 5 (or 0) spines that are shorter than at E. peruviana that can have up to 10, little longer - up to 4 cm. Some consider those as forms of the same species. Alkaloid content also maybe.

Your Ferocactus can be named Ferocactus herrerae as well. Or something else from F. peninsulae group.
If your cacti mess in your job just forget about the job.
°C = (°F - 32)/1.8

Ty for the help!
I guess that the last one is a pachanoi and the cacti in the second could be either peruvianus or pachanoi.
