1.) como se llaman
2.) como te llamas tu
True, conjugation is making the verb agree with the subject
The conditional tense indicates a mood of would or could have accomplished a hypothetical situation or activity. The conditional form for saber is as follows:
Yo sabría
Tú sabrías
Usted/Él/Ella sabría
Nosotros sabríamos
Vosotros sabríais
Ustedes/ellos/ellas sabrían
This is an irregular conjugation. Hope this helps! :)
