How many Native Americans does White Fang encounter outside the den in Chapter 9?

White Fang encountered five Native Americans outside the den.

Before him, sitting silently on their haunches, were five live things, the like of which he had never seen before. It was his first glimpse of mankind. But at the sight of him the five men did not spring to their feet, nor show their teeth, nor snarl. They did not move, but sat there, silent and ominous.
