Random movement of objects in an array/index?

[GameBredDJ]

I have a project due pretty soon and needed a bit of advice. I have to make (let's say) 5 object in an array move randomly in different directions on screen. Let's say you have 5 roaches on a page and you want all of them to move in different directions randomly, how would I go about the? I have no problem creating and adding object to an array. My problem is the random movement of each individual objects. Any help or advice would be very appreciated.
