There's a variety of causes there, that I can see.
Some appear to be plain "vise jobs" - put two coins together under pressure.
Some appear to be "fountain coins" - coins sitting for a while in open water (or something else that's only very mildly corrosive) and two coins of dissimilar metals have reacted.
Some appear to be the result of even more corrosive processes - sitting in Coca-Cola, or vinegar perhaps. Or they may have been in a fire, gotten damaged, and then cleaned up again.
