The human and mutant classes produce the highest HP by far because of how the other classes have fix base stats. Unfortunately, the cap for all stats (Attack/Defence/Agility/Magic) is 99, but equipment makes all stats exceed 99. So, the real cap is 99 + equipment bonuses.
The robot class produce the second highest HP and the cap for all characters is 1195 HP. Robots takes a pretty bad stat penalty, so 99 for all stats and 999 HP and anything over 999 is just calculated as 999, which is the reason robots fall way behind humans and mutants. However, robots also have robotic parts bonus cap of 99 for all stats and 999 hp that adds directly on to these stats, so the cap for robots becomes 1195 HP, 147 Attack, 107 Defense, and 144 Attack with 0 MP. And just like humans, equipment also adds directly on top of those caps, so the real cap for robots is penalized base stats + robotic parts bonuses + equipment bonuses.
The rest of the classes have fixed base stats depending on what form they take, which are lower than 999 HP and 99 for stats, so they're all lower than humans, mutants and robots. Monsters can't even wear equipment for equipment stat bonuses.
