1) Many, many Linux distros (Currently running in my home: Antergos, Fedora, CentOS, Debian, Ubuntu, Proxmox, OpenWRT, Raspbian, LineageOS, Cyanogenmod, Mint) 2) A couple Unix variants...some college labs that I don't recall; brief installs of Solaris and OpenBSD; currently using a lot of AIX boxes at work; and my home firewall is pfSense which is based on a BSD. 3) Various flavors of Windows (and a bit of MS DOS), from 3.1 to 7 (I've briefly touched 8 and 10, but never for more than a few minutes!) 4) Apple...though I think the only Apple system I ever spent any significant amount of time on was a IIE, and that was just the elementary school labs. Mostly including this to take myself out of the 0-3 category, not sure if it should count ;) Occasionally I also have to support people on Macs, so I've touched OS X a few times, but I generally try to avoid that.
Not counting each individual Linux distro because that's too easy, I'd be 20+ from that alone...And those aren't really separate OSes, just variants of the same kernel.
Also not counting different releases of the same OS...might be a new version, but it's still the same OS. Particularly since I'm running a few rolling release, so any attempt to count those would be fuzzy at best.
And not counting appliances because those OSes don't matter. Sure, I've done a lot of graphics calculator programming, and I've done some game console and digital camera hacking, and I'm sure all of those devices have operating systems...but I can't even tell you the name of it and it's pretty much inseparable from the hardware itself. It's hard to say I've "used" an OS when I don't actually know anything about it!

Four that I know of...
