You intend to turn right. Do you have to yield the right of way to the vehicle approaching from the left?

Why?

At this equal-priority junction, drivers must give way to vehicles approaching from their right. The red car approaches from your left, so you are on its driver's right and that driver must give way to you. Your intended right turn does not change this order.
