The first half of what you said is right- the numbering of Princes and Princesses is by the order of birth, separated by gender. There's just two problems with this:

-Nunnally is not 17th Princess. Her number was never revealed.

-Marrybell can't be Fourth Princess, or any Princess, because the Third Princess is younger than her, by two years. She just doesn't fit in, at all. The only way I found to explain her, and that's purely going off non-canon material, is that she may have had an unrevealed twin brother, in which case she would probably share the same number as him (Castor and Pollux are both Fifteenth Princes, but that just might be for twins of the same gender).
