Since mites are very contagious all your rats will need to be treated. The one showing the most scabs is the one who may be slightly weaker than the others. I have 2 boys at home and one is heavily scabbed and the other I cannot find any scabs yet but they both got treated. The one with the scabs also has a URI that hadn't been treated.
As Jo says mites live on a rat's skin naturally (hence the false negative on the skin scrapings), but sometimes they will flare up if the rat is sick or compromised or has been exposed to even more mites (like infected bedding, etc).
Definitely treat your rats no matter if you get the false negative or not.

The Radfordia ensifera is a fur mite that can cause dermatitis. It may occasionally be seen as white specks of dust on hair follicles. This type of mite is most commonly seen in rats. It produces intense itching, and leads to scabs most frequently seen on the shoulders, neck, and face of the rat. The rat fur mite and mange mite do not infest humans or other animals.
Mites under normal conditions are commensal in small numbers and do not tend to be bothersome to their host. It is when the rat is stressed, has a decreased immunity due to other illnesses, and/or is unable to keep the numbers reduced by normal grooming that causes the mites to flourish in numbers. Inattention to proper husbandry, a rat that is ill, or giving ineffective treatment can lead to reinfestation, and dermatitis. It is therefore important to maintain care and follow through with treatment(s) prescribed.

Skin scrapings for possible parasites can be done, however, parasites may still be present even though the scrapings are negative.
