animating array movie clips

I've got an array with four movie clips that I would like to move onto the screen separately (the first one, then the second, etc). Is there a way to do that?

This is the code I have to move the whole array onto the screen:

arrCSnav:Array = [cs1_Button, cs2_Button, cs3_Button, cs4_Button]

for(i=0;i<arrCSnav.length;i++) {

var enterTween:Tween = new GCSafeTween(arrCSnav, "x", Strong.easeOut, arrCSnav.x,arrCSnav.x+180,12,false);

}
