How can I start 2 terminal sessions at the same time?

 
I wonder if I can start 2 terminal sessions at the same time? i.e., one for demo, one for real. Since I know that this can be done using different windows login names, is it also possible to be done under one login name only?
 
Install terminal into 2 different directories.

You cannot manage login name because login name is your account number
