You have came to a great place to ask questions, I don't think Aprophet was being disrespectful to you, the reason I believe that he was asking you that question was because of the list of birds you listed are awesome, but definitely not for a beginner. He didn't know that you raised so many birds in the past and was probably going to help you out but needed to know where to start from your experience level.
It's been my experience that Aprophet is a stand-up BYCer and only wanted to help.
The dimensions you listed are fine for pairs of the quail that you listed before. 2 sq ft per bird is a rule of thumb...not the only school of thought, but a school,,and you have exceeded that. Know they are more flighty than your cots were...they have a big head boink factor, so watch for sharp edges on the ceiling. For cover in my pens I use flower pots on the side, hollowed logs split in half and cut to 16 long and branches about1.5 inch in diameter. This will give them hidy places and cover as well as objects to break up the boredom in a cage.
Congrats again in getting some awesome birds!
Good luck and post some pics!
