False. Physically, you can install up to 4 in a disk formatted with a MBR partition table, as an operating system installation can only use a primary partition, where as if you used a disk with GPT partition table, you may be able to use up to 128 (number is not exact).
Although, if you have a sufficiently-powerful-enough computer with loads of space, you can install as many operating systems as you want with virtual machines.
This is completely false, You can have as many Operating Systems as you want installed. The down side to this is that it does take up a fair amount of memory.
Its not a true or false it depends on your personal requirement,if you have required more then one operating system on your personal computer then you can install no issue.
I have OS 10.5.8 and OS 10.4.11(10.4.11 also has "classic mode" which is actually OS 9) on my old Mac Tower G-5 and PowerBook G-4's and OS 10.9.5 Mavericks and Windows 8.1.1 via parallels on my Mac pro. I think it's not only possible, but often done at least from the Apple side. If I wished, I could add more drives/partitions and also run any of the Unix based systems like Linux, add OS 10.10 Yosemite and any other versions of Windows on one machine. Don't know why I'd want to, but it is available.
You can dual boot a computer or parallel boot. You can install Android OS on USB and change bios settings to boot Android at start-up. Also get Oracle's free Virtual Box to get many OS running in your Windows or Mac etc.
