Can I run multiple processes on admin user account while logged in to another account on OSX Server (Yosemite)?

I am setting up a Mac mini home server as an HTPC and to run other processes (FileMaker Server, web dev server, etc.). I want to make a user with limited privileges to be logged into while Mac mini is connected to TV. However, I want other processes to be running on admin user account while I'm logged in to user with limited privileges. Is this possible or do I have to be logged in to the admin user to run the processes?
