All these questions are given in the simple present. The simple present tense is used to talk about habitual actions or routines. This tense is also used to describe things that happens now or in the near future. So, by answering these questions in Spanish we have:
1. ¿Quiénes están en el muelle?
Yo estoy en el muelle
estoy is the conjugation of the irregular verb estar for the first person singular in the simple present. Conjugations of irregular verbs need to be memorize because there is no any rule for these types of verbs. So the verb estar is being used here as Location, that is, it describes where a person or thing is permanently or temporarily.

están is the conjugation of the irregular verb estar for the third person plural in the simple present. So the verb estar is being used here as Location as well as in the previous question. This answer translates into:

3. ¿Quién va a nadar en la piscina?
Mis amigos y yo vamos a nadar en la piscina
vamos is the conjugation of the irregular verb ir for the first person plural in the simple present. On the other hand, nadar is a regular verb given in infinitive form, that is, the most basic form of verbs in Spanish. So this answer translates into:
My friends and I are going to swim in the pool
4. ¿Qué tiempo hace hoy?
Hoy hace mucha calor
The verb hacer is used when telling the weather. So the conjugation of this verb we use is hace that matches the third-person singular. In this way, this answer means:
Today is very hot
5. ¿Por qué no quiere nadar Susana?
Susana no sabe nadar
This answer is given in negative form. So the verb that is being used here is saber whose conjugation is sabe for the third person singular. Therefore:
Susana cannot swim
6. ¿Qué van a visitar en México?
Vamos a visitar museos
Vamos is used here as in the exercise 3. So visitar (to visit) is a regular verb given in infinitive form. The translation of this sentence is:
We are going to visit museums
7. ¿A qué hora se levanta Pablo mañana?
Pablo se levanta a las siete de la mañana
This sentence is given using a reflexive verb and pronoun. In Spanish, we use Reflexive Pronouns with a verb to point out that a person carries out an action to or for himself or herself. In this way, se is the reflexive pronoun for the third person singular and levanta is the conjugation of the verb levantar also for this person. So Pablo is carrying out the action for himself. Therefore:
Pablo gets up at seven in the morning
8. ¿Qué hace Pablo por la mañana?
Pablo se baña y se cepilla los dientes
This sentence is also given using the same reflexive pronouns as in the previous exercise because Pablo is also carrying out the action for himself here, but other verbs have been used in this answer, that is, the verb bañar whose conjugation is baña and the verb cepillar whose conjugation is cepilla. So:
Pablo bathes and brushes his teeth
9. ¿A qué hora van a desayunar los amigos?
Van a desayunar a las nueve
Van is the conjugation of the irregular verb ir for the third person singular in preterite form. The verb desayunar is given in infinitive form. The translation of this sentence is:

10. ¿Qué se pone Pablo por la mañana?
Pablo se pone una camiseta y unos pantalones
This sentence is also given using the same reflexive pronouns as in the previous exercise because Pablo is also carrying out the action for himself here, but other verb have been used in this answer, that is, the verb poner whose conjugation is pone. So:
Pablo puts on a shirt and pants
