We are trying to run four motors in two motor ports using a vex brain, is their any way to make all four motors move independently? Please help us !!!!!!!!!!!

You are trying to run four motors from two motor ports? As far as I know this is not possible. To run your four motors independently you must plug them each into their own motor port on the Cortex.

Some things that would would be helpful are:
By "Vex brain" are you refering to a Cortex?
What programing language are you using? EasyC? RobotC?
Could you provide a picture of where the motors plug into the brain?
Could you provide the code that you are using now?
