When to let froglets go

[Hidr]

So I have a water source outside and the green tree frogs that live on my porch left babies. I brought five inside. One is now a frog as of today. Still has his tail.
So do I let him lose now in the place I got him from. Wait till the tail is gone? And when? Morning noon evening. It is till warm in the day but getting down to the 50 degrees at night.
thank you for any help?
Maybe I should let them all loose now that I got to watch one grow all the way to a frog.
