Cacti and a couple of leaf succies

[absolute0]

Hello! I need help identifying the ff. :

1. I have a similar cacti which was sold to me as Neoporteria gerocephala (=Eriosyce senilis). Please confirm if it is correct.

2. Cylindropuntia molesta?​ Or Cylindropuntia davisii?

3. I thought this was Astroloba spiralis or Astroloba herrei. Could be a hybrid though.

1 and 2 might be correct, have to see flowers to be sure.

2 = Cylindropuntia subulata

2 = Cylindropuntia subulata

A. subulata was my first though too. But my second thought was it isn't. The leaves would be larger and more persistent if it was an A. subulata

Not A. subulata. (I know how A. subulata looks like). Some Cylindropuntia (cholla) for sure
