There is no limit on RoW as to how many characters you can have. However, the activity guidelines are that you must be able to post at lest once every fortnight. You may have as many characters as you want, but if you do not post once every two weeks with each character, that character will be removed. If this privilege is abused (consistent inactivity/removal/rejoining), you will be asked to limit yourself to one or two characters. We believe that you are capable of monitoring yourself, so keep as many as you can post actively with. Remember it's better to have one very active character than two barely active ones!
