When conflicts started around the early 19th century (the wars between the countries of Spanish America, and the Spanish Rule in Spanish America) they were short-lived with the governing bodies established in Chuquisaca and Quito opposing the ideas/demands/rules of the Supreme Central Body of Seville. When the Central Body fell to the French invasion around 1810, numerous new bodies spread across Spanish America, starting a chain of newly independent countries stretching from Argentina and Chile in the south to Mexico in the north before half of the 19th century passed!

During and/or After the conflict/wars in Spanish America...

Central America gained its independence along with New Spain. On September 15, 1821, an Act of Independence was signed in Guatemala City which declared Central America (this containing: Guatemala, Honduras, El Salvador, Nicaragua, and Costa Rica) is independent from Spain.
Knowing this... We find out the answer is:
The countries that were independent in the Latin American independence movements were Guatemala, Honduras, El Salvador, Nicaragua, and Costa Rica.
