The seated woman. She is the only officer present, and is an O-6 or a Navy Captain. The way you can tell is the 4 full width stripes on her sleeves.

The others are all enlisted, with rank indicated by the dashes on the shoulder. 3 equals E-3 or Seaman.

I will also tentatively identify the woman as Mildred McAfee. She was the Director of the USNs Women's Auxiliary in WW2, better known as the WAVES. She was promoted to Captain during the war as the program and her duties expanded.
