Do you have brownish or brunette hair?

How are your friends? (notice the conjugated verb son comes from the infinitive verb ser)
Check the spelling of the verb "pensar" in the question: ¿Qué piensas? = What do you think?

#2. This is the difference between "¿Cómo están tus amigos?" = How are your friends (health-wise) = sick, tired, etc. and "¿Cómo son tus amigos?" = How are your friends/what are they like? = nice, tall, studious, etc.
