Hola Reyes
lo, la, los, las are direct object pronouns that refer to both things and peple. 
So, the verb "to see": ver is a transitive verb, and what/who you see is a direct object (I see it, I see him, I see them..). You need the direct pronouns here. 
A Miguel y a José los veo todos los días.
Miguel and José, I see them every day.
The structure of this sentence may confuse you a bit as it's using the "a ..." which may make you think of an indirect object pronoun maybe? (les) - but Miguel and José are direct objects. 
I see Miguel and José - I see them - Los veo (los because "Miguel and José" are masculine)
I see houses - I see them - Las veo (las because "casas" is feminine) 
I see a car - I see it - Lo veo (lo because "coche" is masculine)
etc
Here is the lesson for le, les (indirect object pronouns)
I hope this clarified it.
