Hello Tyler! 

You can use a loop, which will make it more easier, or an IF/ELSE statement to help move your circle even OOP(Object Oriented Program) if you want, it would be more easier fo you! 

Hope this is helpful!

One way to do it is to use OOP, like Jessica said. This would involve using this.x and this.y, and this.x+number and this.y+number for other shapes.

Another way to do it is to use push and popMatrix, which is a bit easier (although I do use the former way for simpler designs, this is helpful for more complicated ones). Here is an example of what I mean:

var keys = [], thingX = 200;

var thing = function(x, y){

pushMatrix();
translate(x, y);
ellipse(0, 0, 24, 50);
ellipse(0, -35, 20, 20);
ellipse(-10, 30, 15, 15);
ellipse(10, 30, 15, 15);
popMatrix();

if (keys[RIGHT]){
thingX++;
}
if (keys[LEFT]){
thingX--;
}
};

draw = function(){
background(255);
thing(thingX, 200);
};
keyPressed = function(){
keys[keyCode] = true;
};
keyReleased = function(){
keys[keyCode] = false;
};

I made a code to explain it, you can find it in my profile under projects, it's called "IDK =P", so go to my profile via the link and go into that code to see it (with some instructions, to make it easier to understand it
