Hello!
First of all, many thanks in advance for taking time to answer my
question.

I would like to add 2 additional switches to 1 existing switch, as
I would like to install 2 additional lights. Since I cannot extend the
existing 1 Gang box (it is plastic and no side screw holes for
extension), the only option I have is to remove it and put in a new 3
gang junction box.

Only? You couldn't put in an "old work" two gang box an inch to the
side of it?

However, the challenge here is that the existing junction box is
nailed to the stud behind my drywall. When I open the face plate, I can
see only the junction box, no extra space for my hand to go around to
pull out the nail. Any suggestion ?

Use hammer to destroy the existing box, then pull the screw out ?

I'm not happy with that. What's on the other side of the wall?

Many Thanks in advance.
