These symptoms appear to be a combination of physical injury (that is, damage from something injuring the fruit's skin but not due to pest or disease) and sunscald. The fruit that is more brown than purple could be either overripe or sun-scalded, which can happen when intense sun reaches the fruit surface where it was previously shaded by the plant's foliage.

You don't need to take any action with regards to any type of treatment, though worst-case you'll need to discard the affected fruits, but keep monitoring the plant for watering needs and consider shading it with a light shadecloth (insect netting or a gauzy floating row cover could work) to reduce the light intensity a bit. The fruit with light scarring on its surface in the first photo is probably fine to eat if it finishes ripening normally.
