Как-то так...

var timerIntervals:Array = [6, 15, 30];
var currentTimerInterval:Number = 0;
var timer:Number;
 
refreshTimer();
 
function someFunction():Void
{
    fo2._visible = true;
    currentTimerInterval++;
    if (currentTimerInterval < timerIntervals.length)
    {
        refreshTimer();
    }
}
 
function refreshTimer():Void
{
    timer = setTimeout(someFunction, timerIntervals[currentTimerInterval] * 1000);
}
