Some are missing, I think?
These are the flags I can see in the top row:
Equatorial Guinea, Ethiopia, Fiji, Finland, France, ? (presumably Gabon but the flag is fluttering so we can't see it), Gambia, Germany, Ghana, etc.
So where are Eritrea, Estonia, and Georgia?
List sorted by the official order in which the flags are flown in front of UN buildings:
