Any number of persons may join in one action as plaintiffs or defendants if they assert a claim for relief or one is asserted against them jointly, severally or, in the alternative, in respect of or arising out of the same transaction, occurrence, or series of transactions or occurrences, and if any question of law or fact common to all of them will arise in the action. A plaintiff or defendant need not be interested in obtaining or defending against all the relief demanded. Judgment may be given for one or more of the plaintiffs according to their respective rights to relief, and against one or more defendants according to their respective liabilities.
