Can you put a atoo fledgling with four parakeets?

A family friend who is also in love with birds breed her two atoos and now has two babies and two more eggs. I'm accepting one and I'd like to know if when I get it (sometime right after it's fledged) can I introduce it then leave it with my parakeets. The parakeets have been through a lot of "meetings". Before I had a different birdie but he died so we got a new parakeet. Then later I baby sat a Quaker. So it's not like they've never seen other birds. But can they get along?
