Just like downloading to multiple CPUs you run nios2-terminal multiple times using different instance numbers to identify which one to communicate with. So you just need to connect a JTAG UART to each processor and make sure it is setup for stdout, stdin, stderr in the BSP settings.

Unfortunately you can't start the CPUs in unison. The closest you can get is downloading to each CPU without passing in the '-g' (go) argument to nios2-download. Then when all the CPU applications are downloaded run nios2-download -g (without the elf file) for all the CPUs. This is easiest to do with a script to send the go command to all the processors.
