Help with some IDs

[lockheed]

I have returned to cacti cultivation after few years. However, I was unable to re-identify several of my specimen. Hopefully, someone can help out.

2. A small Saguaro?



3. Lemaireocereus pruinosus / Stenocereus pruinosus?




6. This one has a label, but I can only make out the first word and it does not narrow it down.




7. Mammillaria compacticaulis?


8. Euphorbia pentagona?




Already IDed:

1. I think it's a Ferocactus, but which one?



4.



5.

Not sure about all of them, but #1 is an Echinocactus platyacanthus. #4 looks like either Espostoa melanostele or lanata. #5 is Gymnocalasium anisitsii.

#1 Oh, wow. I'd not figure it out.
#4 Thanks!
#5 I thought it was Gymnocalycium mihanovichii. Are you sure?

My sure-ness is somewhere between "pretty" and "very." I have a few anisitsii and they look exactly like that. I only have them and one other Gymno, though, so someone who's more knowledgeable about the genus might have a correction.

I would also go with G. anisitsii. Mine was that colour before it gave up the ghost entirely!

Thanks, guys That's three down.
I hope someone else can help with some of the rest.

3. You are right, Stenocereus pruinosus.
6. Trichocereus bridgesii (Echinopsis lageniformis) f monstrose TBM (Short joined type)
8. Should be Euphorbia enopla.

#4 I think it's Espostoa melanostele, not lanata -- lanata's central spines aren't as pronounced as yours.

#7 Mammillaria compacticaulis = M. matudae, and I believe you have a match. Yours is on the way to becoming columnar, so this may be in your future:
