8A was my first entry for this puzzle. A more complete list of national flags with one star (courtesy of this video) would include Angola, Nauru, Tunisia, Libya, Guinea-Bissau, South Sudan, Chile, Morocco, Pakistan, Cameroon, North Korea, Vietnam, Jordan, Malaysia, Puerto Rico, Senegal, Suriname, Turkey, Djibouti, East Timor, Israel, Mauritania, Somalia, Ethiopia, Myanmar, Central African Republic, Togo, Ghana, Azerbaijan, Burkina Faso, Chile, Algeria, Democratic Republic of the Congo, and Liberia. (This list obviously does not include flags of sub-national units of government, or other entities.)
