Was gifted pepper plants by a customer who no longer lives in the area- they labeled the pepppers as “Hot pepper” any ideas to what it can be?

As you can see in the picture, the pods have two different shapes. The plants were given as seedlings, so I'm unsure of variety.. any guesses?

The one pod kinda looks like a habenero and the other looks like an aji lemon based on shape and size. Other pods look more like the pod on the right.
