Which other kind of parrots i can keep together with Pi Maximiliani?

Hey. Like in the title. I have Cage 80x50x175.

If you mean in the same cage, then nothing. 50 cm is tight for multiple birds.

 

[Archer90]

Even for one more? They will have around 4-5 h fight time each day.

Nope, unless you have a large aviary, do NOT cage birds together. I have had bonded parakeets together but everyone else needs a cage

I second the suggestion of not housing them together. My BH pionus would not tolerate anyone in his cage. I had an African Grey and they would exchange cages, Hachu would go into Buster's cage and visa versa. But at the end of play time or bed time they knew where their cage was.
If you were to get another cage to add to your flock, I would suggest a bird around the same size.
