In the Peano axioms, it said that 0 is a natural number. But I also find in google that we cannot say it‘s True. Can I consider 0 as a natural number?

Sometimes. There's conflicting conventions. It doesn't really matter one way or the other, so long as you're clear whether the set you're talking about contains 0 or not.
