If no other Vosa are in the world (so you want to remove all Vosas from the world when creating 15 new ones), then you can use this to remove all before adding the new ones: 
removeObjects(getObjects(Vosa.class));
To make it happen after 5 seconds, you can use an int variable as a timer. Create an act method to increase the int variable each act cycle. If you have the speed slider in the middle (speed = 50), you will probably have around 55 act cycles per second (55 ACS). 
private final int ACS = 55;
private int timer = 0;

public void act()
{
    timer++;
    if (timer % (5*ACS) == 0) //every 5 seconds
    {
        //remove all Vosas
        //spawn 15 new Vosas
        if (timer == 60*ACS) //after 60 seconds
        {
            Greenfoot.stop();
        }
    }
}
