3 is Echinocereus polyacanthus var. densus also known as Echinocereus acifer.

4 & 5 could be just polyacanthus.

8, 9, 10 & 11 all look like Oreocereus celsianus, not Espostoa

This is likely the listing I bought off eBay - admittedly 6 years ago - when I was re-starting growing seeds in earnest.

13 & 14 could be the same species. I'd look at Opuntia hystricina v. ursina ( aka polyacantha) direction...

They are the same plant. The one with two stems is the bottom of the one with one stem which has re-rooted after being chopped from the first plant.

Names suggested do seem to look like it. Thanks. (tu)

I think no 2 could be a form of C. humilis.
