Cactus Identification

[globos]

I'm not sure this is the right forum to post to, but as a beginner I'm only allowed to post here, so here I go.

SWIM got 6 nice plants on Easter and would like to know which is Pachanoi and which is Peruvianus. Each cactus has been photographed from the side and from above. Can someone more knowledgeable help?

The order of photos is as follows.

Plant #1 from the side
Plant #1 from the top
Plant #2 from the side
Plant #2 from the top
Plant #3 from the side
Plant #3 from the top
...
Plant #6 from the side
Plant #6 from the top

None of those clearly look like T. Peruvianus to me, although the third one from the top has similar coloration, but the 4th image, which i guess is still that cactus doesnt look like peruvianus to me. Sorry, I'm no cactus expert but I do know my peruvianus, williamsii, and a couple others (although not nearly as will as Torch and peyote).

Any more takers?
