Here's a couple more plants for you to ID. All I know is that they've been labelled as lobivias - meaning that they probably fall under echinopsis somewhere. Anyway, here we go:
No, number one has not yet flowered in my presence. However, it does have several buds growing low on the body of the plant, however I suspect they are several weeks away from flowering.
I suspect that 1st one is L. backebergii though I'd go more with ssp backebergii than ssp wrightiana (of which winteriana is a synonym). The long spines aren't a feature of all forms, so don't expect an unseen plant with this name to have them if you buy one.
The second one's much harder - I'd want to see a flower first.
