Decide whether the command is grammatically correct or incorrect. mi hermano y yo los estamos mirando(a nuestro padre)

The command is grammatically incorrect. This is because the direct object pronoun (los) is plural while the direct object (nuestro padre) is singular. The singular direct object pronoun is lo.

The grammatically correct sentence would be:

Mi hermano y yo lo estamos mirando.
