Hi,
I will help you as much as I can. I can tell you that you're being asked to use periodic trends to sort this mess out. First, lets sort the list into different groups based on the properties that you stated. Now we have the group major groups. Next if you look at the actual periodic table you will see that atomic weight increase going to the right and down. That is as much as I can help you with from here. This is a good resource:

I hope this helps!
