Substituting Patterns in Grasshopper

Hello! I have this base file that a friend sent me. I’ve been editing it with the parameters I needed (I think he put it together or received help from a post here), but I haven’t been able to replace the circles with different geometries or something that adds more variations or iterations. I’m attaching a reference photo. Could someone explain to me how to do it or point me to a tutorial to learn how to do it? Thank you!"
