Team one wins, like the movie. There will be blood, I believe that applies here as well. I think after a long drawn out bloody battle Venom and Carnage would start to suffocate the three others. Spidey is capable of doing this also, but I doubt if he would. Now for the nay sayers, In the Dc/Marvel crossover with the character Access, Venom was transported to Metropolis, and battled Superman. He saw how powerful Supes was and decided to take a diffirent approach, insread of trying to fight him he forced his tendrils down Supermans throat and began to suffocate him. Access then teleported Spidey to Metropolis to help, also just for the nay sayer. A healing factor does not work against suffocation, since there is nothing to heal from.
