Dynamic hair can be imported into 3DS Max and Cinema4D, also, by means of the Reiss Studio hosting plugins (sold separately).

also how can i use the figures from p5, judy ect.

I think, during installation, there's an option to install legacy content. But only the casual versions of Don and Judy are included with P6, due to disc-space limitations. To get the full package, including the nude figures and all their clothing, you'll need to download them from Content Paradise.

Have your P6 serial number within easy reach; you'll need it for verification.
