Miguel y Elena (cerrar) la puerta<span>.
Translation:
Miguel and Elena (to close) the door.
The infinitive must be conjugated according to the subject, which is plural (Miguel and Elena). It must also be in present tense. The conjugation of cerrar for a plural subject in present tense indicative is cierran.
Answer:
</span>Miguel y Elena cierran la puerta.
<span>1a. Voy a las comprar is incorrect.
The correct form would be Las voy a comprar.
</span>1b. Juan va a darlos is incorrect.
It lacks sense in a direct manner. You would instead say Juan los va dar.
2. Before.
You would say Lo necesito ahora. Lo is the direct object pronoun.
3. Yes.
"I will cook it" would be Yo la voy a cocinar. The personal a makes an appearance in this sentence.
