On the ones where the damaged area is facing up it doesn't look like BER to me, rather sun scald. 2nd & 3rd pics are harder to say, does look bacterial but could have been a bug bite or sun scald or something else. Blossom end rot is relatively rare on long thin peppers, especially if planted in the ground unless there are severe soil moisture fluctuations and they are thick walled types. Not impossible but odds are low.
When you see this sort of damage give the fruit 2 or 3 days and observe what is happening. If the area stays a mushy liquid looking site, pick the pepper and cut that region off. If it instead forms a dry scab it can stay on the plant till ripe and may begin ripening quite quickly spreading away from the damaged area.
