Why don't wind turbines turn when there is 2 turning on each side a one in the middle not turning?

This could be due to a variety of reasons. One possible explanation is that the wind speeds may be too low to turn the turbines evenly. Another reason could be that there may be mechanical issues with the turbines that are preventing them from turning. It is also possible that there are variations in the design or positioning of the turbines that are causing them to respond differently to the wind.
