I think this the Servants we see in each battle is just some kind of background/lore for the event. Maybe I am wrong (because I don't read anything in japanese) but this is my theory:

Each "stage" is called "battle": first battle, second battle, third batle, etc. Those are the opponent of Iskander in the event: Hassan, Gilles, Diarmiud, etc. We are his Ionian Hetaroi. Following the stream we are "joining" to the army and helping Iskander in his batle against the enemy.

So... with 5,000 followers in his army he can beat Hassan. With 10,000 he can beat Gilles. With 15,000 he can beat Diarmuid. With 20,000 he can beat Lancelot. (And he can beat Gilgamesh even with thousands of millions because he just use Ea and everything ends XD).
