No, rust is not harmful. However, it's not helpful, either. And, if your dishwasher's racks are the source of the rust, they may need replacing, or you may want to consider replacing the dishwasher entirely (racks tend to cost around $100-150 each). Consider a model with nylon racks if replacing the entire dishwasher.
No it is completely harmless
The rust spots might be caused by rusting parts inside the dishwasher, such as under the 'wand' piece that rotates at the bottom of the dishwasher. Consult your manufacturer's Operating Manual FIRST then a hardware store manager for suggestions; different products can reduce rust---but not remove it completely. The part(s) will likely need replaced for the rust spots to stop on your knives.
just as the dishwasher kills harmful bacteria, the peroxisomes get rid of harmful substances.
