If it is based on the current RN arrangement and standards, you are probably looking at 9 person cabins as the largest quarter, with 4 person cabins for PO/CPO/ extra JO and 2 person cabins for COXN/CERA and officers generally and four single cabins for CO/XO/CBTO and LOGO. There may be some "austere" quarters for short term embark like Enhanced Boarding Parties, etc.
