There are little Snots and Thalya as your initial units: 2
Each of the three factions have 3 basic creatures and 1 titan: 9 creatures for hire, 3 titans: 13
Horde has two techs that allow a creature to upgrade to a different creature: 15
Undead has Zombies and Skeletons that are raised from corpses instead of hired: 17
Then there are 7 converted heroes: 24
And Thalya can summun temporay Shadows: 25

Thus there are 25 unique units you can potentially use in the same game, and 23 simultaneously.

There are also a few creatures unique to scenarios or missions.

well the 2 horde upgrades are just that, upgrades for the base units. the orcs must reach level 4 to get armoured, so its just a level thing, and the gobos must build there suits. also you can convert max 5 heroes thast again -2 to you max counter. and have you taken into acccount that priestresses and there weaker counterparts convert into the same unit exept the hp? same goes for magicans and aprentice, and also for veterans + warriors and the 2 versions of archers.
