Cadet
At least one Academy cadet was assigned to Regula I during Nero's attack on Vulcan in 2258. (Star Trek)
Chef
The chef was killed by Khan Noonien Singh when Khan discovered that the Genesis Device and related data were gone. According to Pavel Chekov, Khan tortured the remaining crew, including the chef, but no one would reveal to Khan what he sought. As a result, Khan went wild, strung the remaining crew up and slit their throats.
Following the arrival of the USS Enterprise to Regula, the chef, as well as the other crew were discovered when Leonard McCoy unexpectedly walked into the chef's dangling arm.
After the murdered crew were cut down, McCoy stated that were not warm, but noted that rigor hadn't set in. (Star Trek II: The Wrath of Khan)
