If you're talking about moving the apps from the folder to outside it, open the folder, long-press an app and move it. It should move outside the folder once you cross the edge of the folder.

 

I may be wrong but I think the OP wants to put the individual apps into the app drawer. To do this press menu then edit and drag the entire folder to the bin. This will "free" all the apps from the folder and put them in the app drawer, I don't think you can do them individually though, only all in one go.

 

Thanks for sharing Dynomot. I'll put that in the Tips and Tricks sticky later tonight.
