My cat is 4 months and over the last week her ears have gotten red small bumps/lumps in multiple areas on the outside of her ears. She doesn’t seem to be irritated by it or sore when i touch them.

At 4 months of age, it seems unlikely that Zeena has allergies, but that's kind of what this looks like. I would be suspicious of a contact allergy, and investigate changing laundry detergent, if you've recently washed her bedding. You can try an over-the-counter anti-inflammatory cream made for pets like this one: https://www.petco.com/shop/en/petcostore/product/cardinal-hydrocortisone-lotion-05 If the lotion doesn't help, I'd recommend a vet visit to see if oral anti-inflammatory medication improves this condition.
