Explanation:
¿Habla ella español? is incorrect, ¿Habla español? In Spanish we change the form of the verbs, we don't use the pronoun+verb as in English. Therefore it would be She speaks Spanish: Habla (ella) español, but we don't say/write ella, we write the declension form.
Dormir (infinitive) ¿Se dormió? (Did he fall asleep?)
Se is a pronoun for the third singular person of the subject. Always use it with a verb
¿Me llamaste? (Did you call me?)
Me is a pronoun for the first singular person of the subject. Always use it with a verb.
