So he sees a limited amount of people. Only those in cells he passes by? They escort him to the shower and no one else is in there? He eats alone. When he goes out for air he's all alone?

If he is in Ad-Seg, his recreation will be in the dayroom, not outside. The dayroom will have a shower that Ad-Seg inmates share. An inmate is usually allowed 1 hour a day to exercise, make phone calls and shower in the dayroom. Usually, there are between 16 -32 single cells in one dayroom, depending on the size of his facility. They are also fed through a slot in their door and they eat inside of their cell.
