Identify These Please

Thanks

Hi Alan and welcome;
My suggestions are:
1. Mammillaria rekoi ssp. leptacantha
2. Mammillaria sheldonii
3. Mammillaria polythele
4. An Echinocereus species, not sure which.
5. Mammillaria bombycina
6. not sure, maybe a form of Mammillaria decipiens
7. Mammillaria matudae
8. Another Echinocereus sp.
9. Mammillaria magnimamma ??

I'm sure others can add to this, or correct my suggestions, as I have suspicions about some as to a subspecies name as well, but some of them are a bit young as yet to be sure, especially 3, 6 and 9.
