I don't think they would be able to. Parrots are relatively hardy in terms of health when you take good care of them and they are certainly quite resilient in terms of recuperation from surgery or disease when they are healthy and relatively stress-free but vis-à-vis a human, they are extremely fragile. For one thing, they would not 'gang up' (this is predator behavior), for another, although the bleeding to death is a possibility, it would be a most freakish thing to happen as furious birds usually go for your face, not your neck or your wrist and, although a furious macaw can do a lot of damage with his beak and claws, it would be fairly easy for a human to hurt it so seriously that they would be unable to continue attacking you. All you have to do is hit it hard enough to stunt it or break a single wing. And, once they are grounded, breaking their neck doesn't even require a whole lot of strength or even knowledge.
I once read a police report where a man had robbed and, in the process, hurt this older guy who had a macaw. They had caught him because he had bite marks all over and were also able to get avian DNA from his clothes (the macaw's blood), both things used as evidence to convict him, BTW. He reportedly told the police that he had robbed many people with pets but he had never in his entire life seen an animal fight so hard trying to protect his human. He actually had to kill the bird because he kept on attacking him even after he tried to flee.
