How do I make my Green Cheek Conure(GCC) Stop Biting?

She doesn't bite me as much(or as hard) as she bites my family. There are other birds in the room with her(two parakeets and one ateil). One of the parakeets is pretty loud, the rest of the birds are quiet. Would it help to put her in a different room away from the other birds. Each bird has its own cage, so they're not really attached. I haven't let her get acquainted with the other birds because a) I want to build my bond with her. b) She doesn't seem to WANT to get acquainted. I have that bitter spray(you spray it on your hands and when you get bit the bird has a bitter taste in its mouth). The only way I can coax her out of her gage is by holding her favorite treat at the entrance of her cage( I never stick my hand in her cage. I wouldn't want a giant hand coming into my house and picking me up.). When I get her out of her cage and she finishes munching on her treat( I don't touch her while she eats), she bites me again. I know that she loves me because I socialize with her through her cage for a couple of hours every day. She's only been a member of our family for about a week( 6 days to be exact). Do you think she just needs to settle in? I've heard that GCC are very affectionate so I hope that this biting phase pes. If there is any technique to taming my birdie please tell me. I will take each and every answer into consideration.
