not with budgies, absolutely not....under no circumstances house them with budgies...budgiesare very aggressive..in fact, I wouldn't house budgies with tiels either for that same reason...but finches and tiels might get along....but I would not advise housing them together...finches are normally such flightly little fuss budgets...tiels are pretty laid back...I would not house them together for that reason..I think the little finches would drive a tiel nuts.
