The image exhibits perspective distortion sometimes referred to as "keystoning" - the camera is tilted upward relative to the horizon, so vertical lines converge as they go toward the top of the image. If you only want to correct this on the "right" side of the image, where would the "correction" stop as you move toward the left side of the image? The camera is also rotated (clockwise if viewing the camera from behind, looking through the viewfinder) which also adds to the issue.
You can try the ACR filter "Upright" tool and see if that gives you the look you are going for. In the process, you may lose image area on the edges because of cropping during distortion correction, and you may have to scale the image vertical to reestablish proportions of the objects like the chandelier.
You can also use the Puppet Warp Tool to make arbitrary warps and distortions to the image. You can pin the image elements on the left that you do not want to change and then apply a few pins on the right and move them until you achieve the desired effect.
