Sorry, I can't help but think that this is one of the more foolish questions I've read in a while.
The pattern Singleton means "I only want one of these in a single JVM". If you want multiple instances, or even a restricted number of instances, then rewrite the class (something like this):
public class LimitedEdition
    public static final int MAX_EDITIONS = 3;
    private static int numEditions;
    public static void main(String [] args)
        try
            if (args.length > 0)
                int numEditions = Integer.valueOf(args[0]).intValue();
                for (int j = 0; j < numEditions; ++j)
                    LimitedEdition limited = new LimitedEdition();
                    System.out.println(limited);
        catch (Exception e)
            e.printStackTrace();
    public LimitedEdition() throws InstantiationException
        if (numEditions < MAX_EDITIONS)
            ++numEditions;
        else
            throw new InstantiationException("Only " + MAX_EDITIONS + " instances allowed");
    public String toString()
        return "[ instance # " + numEditions + "]";
