This may sound like a weird question . My brother has a male lorikeet and i have an IRN of unknown sex. They just meet for the first time and the lorikeet did some sort of mating dance lol,and seemed really interested in the IRN. My IRN just got angry and tried to bite the lorrie through the cage and hissed at him. I know they are different species but could this mean my IRN is female? Can other species tell this lol

Not sure it means anything. My girlfriends lorikeet Bundy does this to Jordan our male IRN. Bundy will arch and raise up really tall and makes a strange repetative sound.

But like i said earlier, I have my gut feeling from the pictures you posted that your lutino is a female. This of course is impossible to tell simply by a photo, the only other way to tell is by display of sexual behaviour.

I posted some vids of my birds displaying on this link, you can watch out for these behaviours appearing even pre maturity (pre ring) stage.
