I'm new here, so sorry for any inconvenience/misunderstanding. I want to have 4 motors that will all turn 90 degrees forward then stop on a button. Then when the same or different button is pressed, the motor will reverse 90 degrees back to the original position. Any help or advice would be greatly appreciated. Thanks.

For only 90 degrees of rotation, I would consider a push-pull solenoid operating a bell crank mechanism.
Could be done with end stops and micro-switches cutting power when it reaches the 90 degrees. As for turning back either have a second button powering the motor in reverse, again, switched off by a micro-switch.
