Guess the country/continent/colony/polity by its name in my conlang: names beginning with A

Most of these should be pretty easy but you still may wish to spoiler your answers. Depending on how this goes I might share the B's tomorrow, and C~E the day after that, until I've gone through all the names I've come up with.

Today's list includes:

• 3 continents
• 9 UN member countries
• 1 partially recognized non-UN member country
• 4 colonies^[Perhaps I'm using this term a bit loosely. I'm thinking of territories that are politically, economically, militarily, and/or diplomatically subordinated to a geographically distant metropole/"mainland".]
• 1 disputed territory
• = 18 names in total

Unsolved names are bolded.
