Why would you want more than one mouse on a port?

If you are referring to legacy serial mouse ports (com1, com2, com 3, com4), this is usually a limitation of the software mouse driver. Your average serial mouse driver is designed, for legacy reasons, to only look for input from one specific serial port.
Although it was possible to have up to 4 legacy serial ports, they all shared only two IRQs, so you could effectively only have two simultaneous serial devices running anyway. That made anyone using more that one mouse an unlikely occurrence.
So most mouse manufacturers never built in multiple port support for their mice. But since it is possible to have at least 2 unique legacy serial ports on any system, It should be theoretically possible to write a driver to accept input from two serial ports simultaneously.
I just haven't run into any of such mouse drivers. And nowadays with the ability to use multiple USB input devices, it would be more work that it's worth. It would be easier to just get two USB mice instead. Or one PS/2 and one USB mouse.
