Royalty or not, I can't say I advocate using 5 or 6 or more names for one child. It's a bit of overkill if you ask me. :b
However, I do like these individually....
Leonor Maria Isabel AntoniaIngrid LouiseAlice Madeleine Therese Amelie Josephine - this is my favorite, I think
Caroline Louise Marguerite - Nope, this is my favorite :)
Charlotte VirginiaCatharina-Amalia
Beatrix Carmen Victoria - this one's nice, too
InesGeorgina Nora Mathilde Claire LouiseBeatrice HelenaAstrid Laura Beatrix Anna PilarCécile
IreneTheodora
A lot of the same names are repeated, eh? :-/ And
Alexia for more than one princess? Yikes.
