3) Try to Use "DAZ's Mike 4 - Morph injections - Hiro 4" from Poses Library - but they dont work! Like @Curved Blinking@ or Realistic face for example.

Morphs from dials work, but they are distorted.

The morph injections won't change the figure until you apply them using the dials. The morph injection "pose" just adds the dial to Hiro. You have to adjust the dial to see a change in the figure.

I never use those individual morph injections. You can just inject them all at once using INJ Hiro 4. The individual morph injections date from a time when computers were much less powerful than they are now. People injected only the morphs they needed, to save system resources.
