This is not really anything specific for Angular. You just need Array.prototype.map:

var data = [{"email":"[email protected]","pass":"Doe","name":"John" },
{"email":"[email protected]","pass":"Smith","name":"Smith"},
{"email":"[email protected]","pass":"Jones","name":"Jones"}];

var names = data.map(function(user) {
    return user.name;
});

document.write(JSON.stringify(names, null, 4))

However, here is piece of Angular advice: don't use $( "#tags" ).autocomplete in controller, create dedicated directive for this DOM stuff, controller is not the place for this.
