acquired cacti in decline

[dattdude]

Hi I acquired these four cacti and two euphorbia from an estate after they went well into decline. Im trying to identify them. I think the first one is a mature gymno horstii. The fifth plant a euphorbia enopla but notice the thorns are black not red with the exception of one or two. The fouth plant a euphorbia submammillaris and i have been looking at pictures to identify plant numbers two three and six but i havent found matches yet. I re-potted most of these but i want to identify them before administering water (epiphany after the fact) to be sure i used a proper medium for each plant. They were all in a heavy peat mix with sand i think. The substrate was nothing like i would use. However the first plant seems happy and is clumping, notice also the spines on this plant are black except the newest one which is a tan color. Ok, thanks cacti people!

The first one is a Gymnocalycium. G. hosrtii? Looks like it should be OK if it has roots.

2) cleistocactus straussi?
6) Parodia Scopa?

Thinking the same as Pilif

cleistocactus strausii on #2 is possible but the older parts of the plant appear yellow and not silver and the columns are only about the diameter of a nickel. Perhaps due to poor growing conditions?

Parodia Scopa have white spines right? The snowball cactus? Cactus # 6 is a rich colored yellow and much more stubby columnar than globose but that is hard to see from the picture taken looking down on the plant.

Any input on # 3. thick black spines and suppose to be green but looks sunburned and water starved.

Parodia Scopa have white spines right?

Some have only white spines, some have both white and red(dish) spines.
