* "kien" should be "quién" (who)
* "eres" is the correct conjugation of "to be" (are)
* "komo" should be "cómo" (how)
* "t yamas" is incorrect. It should be "te llamas" (your name is)
Corrected sentence:
¿Quién eres? ¿Cómo te llamas?
This translates to "Who are you? What is your name?"
It's important to note that in Spanish, the question "¿Quién eres?" is usually used for formal situations. In informal settings, people would typically ask "¿Cómo te llamas?".
