Whitewalkers are apparently all the full grown versions of Craster's incest babies that have received a kiss of death from frozen Darth Maul?
Considering they've been around for thousands of years, nope. As Wollip said, the central one was confirmed as the Night's King, but there's more. Look at this:
The Night's King approaches from the centre, and the Night's King was the thirteenth Lord Commander of the Night's Watch. There are thirteen figures in all.
This has basically confirmed that the Others are a race or a people, with some kind of ruling council. I read a very interesting theory the other day which basically stated that at the end of the Long Night, the Others were not defeated, but rather agreed to a treaty with men. The Last Hero was a diplomat, not a conqueror, and the Night's King married a female Other to seal the deal. The Night's King was a Stark, and as part of the treaty his family would rule in the North, as a kind of buffer zone between men and the Others. Therefore,
there must always be a Stark in Winterfell. The Starks' words, "Winter is Coming", are not a warning, but a threat, as in their line they have the blood of those who can control winter and ice itself (Ned was fine with sleeping naked in Winterfell, just as Dany was fine with the scalding hot bath).
The Others helped Brandon the Builder construct the Wall to enforce this treaty (how on earth could men construct something like that with no magical help), and since the Others were winning the war at the time, they demanded tribute in the form of humans sent north of the wall to become White Walkers (as we've just seen with the baby). That was the original purpose of the Night's Watch (and where the practice of ranging north of the Wall came from) - the scum of Westeros were sent north as tribute. Over time, this treaty was forgotten by men, and Craster later stumbled accidentally on the human sacrifice aspect - thus why the Others did not touch him. Men forgot, but
the North Remembers.
