Having a bonfire and threw 3 aluminum cans in. after they melted is it possible to get aluminum poisoning from the fumes of them?

Not likely: Here is a fascinating study of fumes from campfires down by the Rocky Mountain Forest Service. Metal fumes in garbage thrown into campfires that appeared to be a problem were cadmium (from batteries), lead, beryllium, and mercury. See http://www.fs.fed.us/t-d/pubs/htmlpubs/htm04232327/page01.htm

No: Not enough exposure. You were outside and didn't ingest and aluminum. All the best.
