If you watch the 1.0 opening movie, you can see dozens upon dozens of Primals being freed from beneath Silvertear Lake. There can't be only one Primal per element with how many of them. There's nothing that even says they have to be elementally aspected. There could even be astral- and umbral-aspected Primals out there.

I always thought Fenrir was going to end up being the Primal of the Lambs of Dalamud. In the lore, before Dalamud came crashing down, it was known as the Hound of Menphina (the moon). If they'd chosen to make him a Primal, Fenrir could've been an umbral ice Primal.
