2. Órganos
3. La Isla de la Juventud
4. Ballet Nacional de Cuba

Explanation: Just to elaborate a little on the answer, it can be added that in this exercise they are asking you to translate into Spanish certain words that are part of a description of Cuba and its capital. Although some of the words are very straightforward to translate, as they are similar in English and Spanish (Palacio de los Capitanes Generales, Ballet Nacional de Cuba, Colonia), others require a little bit more knowledge, such as Puros and Isla de la Juventud.
