Will Gouldians breed if there is more than one pair in an aviary of about 8m2?
If yes, what is the maximum pairs for me to have?
Thanks

Yes.
Bad idea to look for the maximum you can put in any aviary. Reality is, you could probably put over a hundred in there, however they would have a horrible & hazardous life.
If you want a nice Gouldian aviary with reasonable chances of breeding them well, I would go for an absolute maximum of 3 pairs, ideally 1 pair.
Good luck.

As Tiaris has said; fewer birds leads to better breeding results.

If optimal breeding results aren't your primary goal, and you'd rather just have a nice collection of birds to look at, you could probably go up to six or seven pairs of finches in a 4x2 aviary; assuming the aviary is well thought out.
