The questions are not very well-formulated and are too general. Please specify the map, your opponent (Castle and Hero), and their approximate development.
I will try to explain it simply:
1. Humans are the most balanced and easiest race to learn. They can compete with any Castle, especially in the late game. The longer the game lasts, the greater the advantage for Humans due to unit retraining. The strength of Humans lies in gold; if there is gold for retraining, Humans are strong; if there is no gold, there is no point in playing as Humans. Orcs weaken in the late game; armies grow, damage increases significantly, and Rage is recovered faster, meaning Orcs have no advantage.
2. There are no best or worst. Different Castles are effective at different stages of the game. For example, Dungeon is very dangerous in a fast-paced game, but it is completely harmless in a long game. However, Academy is almost impossible to defeat in the late game, but it is quite vulnerable in a fast-paced game.
3. It is essential on such maps. "Sharp Mind" in the Logistics branch is a particularly good skill, and Humans do not need education to acquire it.
4. Hive is the most protected Castle against Dark Magic in the game. Two units (Paladin and Inquisitor) can remove control effects, plus a Hero with Light Magic. Therefore, Light Magic is essential to develop! Weekly unit retraining depends on the Hero you choose. If it's Laslo, retrain into Armored Archers; if it's Dugald, retrain into Crossbowmen; if it's Axel, retrain into Knights if possible; all other Heroes should retrain into Monks. The more, the better.
5. Humans are a one-sided race; the tactics against any Castle are almost the same. It only differs depending on the Hero you choose and how the Dwarf has developed. If there is gold, there is an advantage; if there is no gold, Humans have nothing to offer.
6. It is quite possible. Necromancer is not the strongest race in the game, unless the map has many Castles. The Necromancer doesn't care which Castle it is; it turns everything into undead. However, Hive only benefits from its own Castle.
7. It is not worth it.
8. Again, it all comes down to gold. If there are many gold mines on a large map, prepare Knights and Axel. If you feel that you cannot afford to retrain Knights, a budget Laslo with many Armored Archers will be just as effective as Axel with Knights.
