The figures came with the ZBrush connection. 

The Poser License says:

'- “Unrestricted Content” means Content included with or part of the Program that is specifically identified in the Documentation or listed in this EULA as Unrestricted Content.  The following figure geometries and their associated textures are Unrestricted Content: low res male, low res female, medium res male, medium res female.'

'... Company grants you a limited, personal, nontransferable and nonexclusive license (without the right to sublicense):
a. To reproduce, prepare derivative works based upon, distribute, publicly display, and publicly perform the Unrestricted Content for any lawful purpose other than to create a product which is intended to compete with the Program or to create new content which is intended to compete with the Restricted Content. ...'

I read this, SM please correct me when I am wrong, as saying that you could use those figures to produce your own figures, which you are then free to distribute as long as they  are not part of a program intended to compete with Poser or figures pretending to be any of the Poser native figures. 

Any other interpretation would defy the purpose of this content.
