The pictures are so poor, I wouldn't hazard a guess. Try increasing the light level, and get closer if possible.

Number 1 looks like A. myriostigma. More light would help

Re: Is this an astrophytum nudum?
If you are not photographing for backlit effects don't normally take pictures with the light behind the plant since it will make the side of he plant towards you too dark unless the exposure is corrected, something most snapshotters do not do. Take it with the light towards the rear of you so the nearside of the plant is being lit by the light. Even take it outside to photograph if needs be.
Looks like a nude form of Astrophytum, but these are not really varieties or subspecies, probably best just considered a "forma" or f. nudum since all of the Astrophytum species can vary in the amount of floccose spotting and produce fully nude forms.

Simply variation in a species just like 3 ribbed Astrophytum myriostigma's which may retain this characteristic for a time but may eventually produce a fourth rib much to the owners annoyance!

2nd is some Eriosyce on steroids IMHO.
But hope is always there where life still is.
Recommend to replant poor plant in normal cactus substrate, to pick off all pups and to give much sun.
Next year in good shape with flowers to show again.

Re: Is this an astrophytum nudum?
If you have moved your plants from a low light area to full sun, beware you don't sunburn them. They need to adjust to increased light levels over a period of time. Increase the light intensity/duration a little bit each day for up to two weeks. Noon is the brightest.

OK, but the caution still is there. It is easy to scar your plants. I've done it too many times.
