Are there any other main rays in the electromagnetic spectrum, that are harmful besides UV rays, Infrared Radiaton, Gamma Rays, and X-rays?
All radiation can probably cause some problems, in high enough doses. Its just that what consititutes “high enough” is different for each. Microwaves can literally “cook” you! (That’s what a microwave oven does!). But you need a high intensity. Even visible light, if intense enough, can blind you (even if your eyes are shut). But we don’t normally encounter such high levels of microwaves or visible light.
