Need help with snapped pieces

Best friend's girlfriend snapped up my necron army and I am looking to restore them as best as I can. Looking for tips, this is my first and only "army".

Long story short she hates me and decided to snap up all of my pieces when I moved out of their place last year. I kept them but until recently havent had the heart to try to fix them.
