I have this content: 
 public void thankYou()
    {
        getWorld().addObject(new BgItem(14), 455, 115);
        getWorld().addObject(new BgItem(15), 610, 115); 
        getWorld().addObject(new BgItem(16), 785, 115); 
        getWorld().addObject(new BgItem(17), 432, 172);
        getWorld().addObject(new BgItem(18), 557, 172); 
        getWorld().addObject(new BgItem(19), 773, 172);
        getWorld().addObject(new BgItem(20), 410, 231); 
        getWorld().addObject(new BgItem(21), 496, 231); 
        getWorld().addObject(new BgItem(22), 673, 231);
        getWorld().addObject(new BgItem(23), 496, 287); 
    }
How do I display it one at time without using Greenfoot.delay(int)?

Do you mean for it to add the next BgItem each time thankYou() is called? Or when thankYou() is called, they all get added, one after the other given some time interval?

Something like this would work: (not tested) 
private final int[][] BGITEM_LOCS = { {455, 115}, {610, 115}, {785, 115}, {432, 172}, {557, 172}, {773, 172}, {410, 231}, {496, 231}, {673, 231}, {496, 287} };
private final int PAUSE = 50;
private int step = -1;

public void thankYou()
{
    step = 0;
}
public void act()
{
    if (step != -1 && step++ % PAUSE == 0)
    {
        int i = step / PAUSE;
        getWorld().addObject(new BgItem(14 + i), BGITEM_LOCS[i][0], BGITEM_LOCS[i][1]);
        if (i == BGITEM_LOCS.length - 1)
            step = -1;
    }
}
