Americo-Liberians and Sierra Leone Creoles are descendants of African Americans, I don't know too much about the other groups.

1. Yes. There are Korean-Americans, Vietnamese-Americans, Malaysian-Americans, etc.
2. No.
3. Yes. There are Mexicans, Argentinians, Brazilians, etc.
4. No. African immigrants are *not* African Americans just like how European immigrants are *not* European Americans. They are labeled according to their country of origin. Since Africa is a continent and not a country, they would be labeled according to their country, for example an African immigrant might be an Ethiopian-American or a Congolese-American.
