Use a 'switch' block:

for(int makeJordan = 0; makeJordan <=11; makeJordan++)
{
    firing = true;
    jordanCount++;
    int Y = makeJordan *25;
    Actor actor = null;
    switch (makeJordan) {
        case 0:  actor = new Jordan(); break;
        case 1:  actor = new Jordan2(); break;
        case 2:  actor = new Jordan3(); break;
        // etc.
    }
    addObject(actor, 575, Y+10);
}

Make sure you have all 12 cases (case 0 through case 11) or a NullPointerException will be thrown.

thank you so much for the reply but I have another question, when I tried to implement this code into my game it said that Jordan2() was not defined? also how would I individually call these objects?

Maybe you were unclear as to what you wanted. The 'Jordan2' and 'Jordan3' were class names I gave the other spawned actors. Apparently, what you want is to spawn a bunch of Jordan objects and keep references to them. In this case, you would simply have this:

// array field
private Jordan[] jordans = new Jordan[12];

// with this loop
firing = true;
for (int i=0; i<jordans.length; i++)
{
    jordans[i] = new Jordan()
    addObject(jordans[i], 575, i*25+10);
}

Line 8 shows how you can refer to them. Use any value, 0 through 11, in square brackets after 'jordans' to reference one.

Sure. For example:

int rand = Greenfoot.getRandomNumber(12);
jordans[rand].setImage("Jeremiah.png");

Do not worry about the name of the file -- it is whatever image you want to set the one actor to. Another example (like from an actor class, not Jordan):

Jordan jordan = getOneIntersectingObject(Jordan.class);
if (jordan != null) jordan.setImage("Jeremiah.png");

haha ok im stumped again, i can't seem to get the shot actor to be removed from the world when it touches the JCurse

        if(isTouching(JCurse.class))
        {
            getWorld().removeObject(this);
        }

that is the code that should work right? it worked for removing the JCurse, just the two cannot collide and then both dissapear.

Surely, you can have both disappear. You cannot, however, expect one to remove the other after the other has already removed the one. Only put collision detection between the two in one of the two classes. Have the actor remove the other and then remove itself. For example, in the shot class, you can put:

if(isTouching(JCurse.class))
{
    removeTouching(JCurse.class);
    getWorld().removeObject(this);
}
