is a wall a conductor?
A wall is insulator
That depends upon what it is made of.
Well it was a lab and the balloon was a insulator with a negative charge it was attracted to the wall so does that mean the wall is a insulator or conductor
Yes
On an insulating wall, the negatively charged balloon will induce a polarization in the wall that will attract it to the surface.
If the wall were conducting, the balloon's charge would eventually leak to ground. There would be an initial attraction but it would not last.
For a while, the balloon would be attracted to either a conducting or insulating wall

no
A wall is a insulator because the negative charge of a balloon cannot spread
