I have a few more in need of names...

These three Mammillarias came from friends of mine, without IDs. Unfortunately, two are without blooms, so it will probably be a bit harder to identify them. Any help is appreciated, thanks.

OK, I'll have a go.
#1 could be M. haageana
#2 could be M. pettersonii or wagneriana
#3 could be ?? not sure.

Thank you very much, Chris! #2 very much looks like M. wagneriana to me, now that I've seen some pics with new growth - that seems quite characteristic to me. M. haageana is what I thought about #1 too, but that was just a hunch

Hopefully, someone will recognize #3 too, do you think it's a hybrid?

#3 could be a M. sempervivi form, what do you think Chris?

Coming back to this thread, I would also suggest M. columbiana for plant 1, as it is quite yellow spined, a possibility to look into anyway.
For plant 3, I think that the suggestion of something like M. sempervivi is in the right direction, but I would put it closer to M. formosa, maybe the pseudocrucigera subspecies. M. formosa is a very variable species.

 Copy? # 3.
When the bloom, make photos. It is interesting to look at.

Hey PVV, looks quite similar. Hopefully there will be some flowers soon on both of them and then we'll see

Here's #3 in bloom today:

I have no buds. . Chris Davies probably right - this formosa.

Thanks, PVV. My plant was getting woolier and woolier before the buds formed, so that might be a good sign that it is getting ready to flower.

#2 is starting to flower too, so I'll post some pictures of it with flowers soon.

M. wagneriana.
