There are a few violations here, and the code calls for protection from nails, screws. etc., when the cables pass through a stud where there is less than 1-1/4 inches from the edges of bored holes, and when they are run in parallel with the stud, joists, or rafters.
The staples are likley to cause damage because they appear to be driven with a sledge hammer!
I always recommend using "insulated" staples.
The two gang nonmetallic box may also be too small, and that will be the subject of another discussion here.
Please feel free to add your comments, they'll be in the interest of safety!
