"How is this ("each of everyone of you") different from "everyone of you"?"
It's "each and every one of you" - it's more emphatic than "each of you" or "every one of you" (in this case "every" and "one" are not written as one word - the word "one" has a stronger emphasis than in the combined word "everyone"). Another way of making a similar emphasis is to say "every single one of you".
