Partition wall studs not plumb
The wall is not load-bearing. The angle of the studs is not a structural problem, but they cannot be unseen. If it's going to bother you you can attempt to fix them.
To straighten those studs you'll need to detach the drywall. That's potentially messy.  Maybe you can cut the drywall nails with a hacksaw blade, hammer the studs to the correct location then toe-nail the studs in position and finally glue the drywall to the studs. Or maybe you'll make a mess of the drywall, and have to fill some holes or replace it. To keep things interesting that cable and those boxes are going to complicate matters.
