Looks correct to me. You also have crossed out point 3 in your attachment, but didn't mention it in your post here.

Ohhh yess, i don't know what's happening at 3 either.

How did you come to the answers that you gave in your first post?

Therefore, using the right hand rule, the direction of the induced current can be determined. Place your right hand with the thumb pointing in the direction of the magnetic field and your fingers pointing in the direction of the motion of the conductor. The direction your palm faces represents the direction of the induced current. In this case, at point 2 and 4, the induced current would flow out of the page. This is because the magnetic field is pointing into the page and the motion of the conductor is to the left, resulting in a force on the electrons in the conductor to move in a direction perpendicular to both the magnetic field and the motion of the conductor. This creates an induced current in the opposite direction of the conventional current.
