Quote -  i don't think the orignal mt5 ,mc6 are redistirbutable so do i need then to create only pz2s 

This is still unclear.

If by 'the original mt5, mc6' you mean the ones that came with a purchased item, of course you can't resell or redistribute because it's not your work.

Or are you wondering if mt5, mc6 and pz3 files have different rules about their use? They don't.

If you're creating everything yourself (textures, node settings etc.) then you can provide any of the above file types to bring them into Poser.
