If you're using Unity, you need an app that can export to FBX format. You could even use Blender for that, I assume (it's free). No need to use that many apps unless you need to do something very specific. How to import the assets depends on how your engine works.

Poser models are not suitable for games because their polygon count is way too high. Besides, the Poser figure license doesn't allow using assets in game engines because geometry could be extracted somehow.
