Hulk and juggernaut win. Atlas is strong, as in he lifts, but he is not nearly as agile as Hulk or Juggernaut. Plus, as we all know, the angrier Hulk gets the stronger he gets. Theoretically, this gives Hulk near unlimited power compared to Atlas's limited. Samson is just a powered down Hulk (not only in terms of strength but also healing factor) , so after quite a bit of fighting Hulk wins. Juggernaut has no real purpose in this.
