Excluded the British part of Antarctica that's only 27.500 km2.
That's still 10 separate territories with native inhabitants and doesn't include the Crown Dependencies. It also doesn't count the displaced natives of the BIOT, and counts St. Helena, Ascension, and Tristan da Cunha as 1 territory instead of the 3 they actually are.
Doesn't really matter how you count. Whats left of the mighty British Empire is small change.
BOT have 350.000 inhabitants. Vs. New Caledonia alone is 262.000. Puerto Rico is 3,6 mio.
If we are counting this by area wouldn't your nation top the list?
Greenland is roughly the same size as India, so yes.
