There is a widespread Eurasiatic theory that puts all these families (except PIE) into one group, the case for common numerals for one and two seems more plausible. I also add Chukchi-Kamchadal family hare as it is considered close to PIE. I do not include word forms which seem not to be related.

ADDENDUM
I did not include Uralic here even though it is usually considered related to PIE because the Uralic numeral for two is a cognate with PIE word for a pair (q̆eta̯), and the numeral for one seems to mean "non-paired" and come from the same root.
But if we consider the PIE word for four, q̆etu̯ores, we can analyze it as a compound q̆et-du̯or-es, that is "a pair of twos". Thus the most ancient PIE form of the word for two was possibly du̯or (possibly used with nouns with r/n stem?).
