Also very nice
If you don't know how to arrive at these answers then I suggest this is not a project for you at your current level of expertise.2. What transformer i need to get the full power from this amplifier ?
3. How much maximum real power can i get from this amplifier (RMS) ?

Agreed. Class AB is not really suitable for these power levels anyway. Class G/H is not simple to build either. If you really require this sort of power level, you are far better buying a commercially made amplifier. If you buy a second hand one in good working order, it will be cheaper than anything you can DIY.
Almost every commercial amp will be cheaper and maybe even better than DIY.
The less experienced someone is the more likely he is interested in multi hundred Watt or kilowatt designs. (Looking at myself... )
Why is class AB not suitable for 400W? I built a class AB amp with twice the power. As a side effect you have a great heater, good for the winter months. Your cat might love it.
DIY is for learning something and for the fun of doing it. Not for saving money.
Exactly.Many people want to DIY such powerful amps because they think it will somehow be cheaper. It isnt.
It is. Stereo idle power waste is 360W or something.800W in Class AB? It's ridiculously inefficient.
Honestly, who needs 800W at all? Or 400W? This is for PA use. One can get a PA amp from 300 Euro.If you really need 800W, you should be looking at Class D.
