Well, if we translate your first question, written like the main question, into Spanish it's: "Tengo una amiga chilena que se llama Ana".

I am going to guess that you want to say: "Carmen is a Cuban and she has a Chilean friend called Anna." If so... Carmen es cubana y tiene una amiga chilena que se llama Ana. If not... please rephrase your sentence so that it is clearer.

Do you mean child? Or from Chile? If not then, what you have there is "Carmen es Guban, y tiene una amiga de Chile." Or if you meant child: Carmen is Guyana, y tiene una niña como amiga."
