Back row, second from right is M9 — similar internals to M8 (the first four, before the MY), but taller, and with "shortbread fork marks" in the upper shell (just looks a bit like that to me ;-) Top-right is either "M6" (M6x switches from the 70s) or M7 — the difference remains unknown, as the catalogues show them outwardly identical before the M7 design changed in later years.
The two front rows are all clones (they don't have "Cherry" written on them). The first two yellow ones (paler shade) are probably [wiki]Kaihua PG1511 series[/wiki] (branded "Kailh" or "PG1511"), but it's hard to be sure. The front-right two white clones appear to be [wiki]Aristotle Cherry MX clone[/wiki] switches (used by Chicony, who refer to Aristotle as "Yali"), which are discontinued; Aristotle had no information available when I enquired, but from what I understand, you can swap parts between MX and Aristotle.
I added at least most of ysb8433408's extra variants to the wiki a while back, but what we need is for a Chinese speaker to try to find out as much as he or she can from ysb8433408, as most variants are unknown, and ZF apparently retain no record that any of them ever existed. The orange one with a custom cross is covered by MouseFan here:

I covered previously the conditions for re-posting MouseFan's images to the wiki; it would be nice to have ysb8433408's too, as he has some ultra-rare switches.
