Bennett (Rear Admiral) — Admiral Bennett in 2373

The following were stated to be admirals, and therefore hold ranks between fleet admiral and rear admiral. Those with conflicting ranks are presented here.

Archer, Jonathan (Chief of Staff)
Barnett, Richard B.

Barnett appeared to have been stationed aboard the USS Exeter, possibly commanding the Ninth Fleet.

Bennett (Judge Advocate General)

Bennett wore the rank insignia of a full admiral, but was addressed as a "rear admiral".

Brackett wore the rank insignia of a vice admiral, but was addressed as a "fleet admiral."

Given that Colti outranked Admiral Veta, Colti could not have held the rank of rear admiral lower half.

Comsol, Robert L. (Commanding officer, Starfleet Command)
Douglas (Earth Starfleet)
Drazman (Commanding officer, Proxima Maintenance Yards)
Fitzgerald
Gardner (Starfleet Command, Earth Starfleet)
Gilhouly
Gupta
Hahn (Superintendant, Starfleet Academy)
Hastur
Komack (Sector 9)
McCoy, Leonard H.
Mitchell (Starbase 97)
Mitsuya
Moore
Namimby (Starfleet Command)
Narsu, Uttan (Starbase 12)
Nechayev, Alynna

Nechayev only wore the rank insignia of a vice admiral, despite being promoted and referred to as "fleet admiral."

Ngomo
Nogura
Piller, Michael (Starfleet Command; Starfleet Exploratory Division)
Raner (Chief, Starfleet Security)
Gene Roddenberry (Chief of staff)
Shanthi (Starbase 234; Starbase 247)

Shanthi wore the rank insignia of a vice admiral, but was addressed as a "fleet admiral."

Given that Veta was outranked by Admiral Colti, Veta was likely not a fleet admiral.

Westervliet
Wright
Yacobian, Brad (Starfleet Administration; Starfleet Command)
