Identification: Anyone know what cactus these are?

Need a hand identifying these little beauties that I picked up at a garage sale

 

Various forms of Echinopsis , and the last two resemble oxygona and eyresii. A more precise identification is impossible, because of extensive hybridization between these species and others.

 

Thanks mate. There are just the two types. The flowering pics I didn’t buy, but mothered all the smaller examples.

The seller asked me what they were. She sent me the pics to show me the flower. She’d been told they were Cereus peruvianus, which I knew was wrong
