Is there any way in After Effects to:
convert a Character Animator scene
to After effects native shapes with keyframes??
I don’t think so. Character animator does all sorts of warping, effects etc that is not in AE. You do do something things like scale and transpose, but I don’t think you can distort and bounce things. You can overlay multiple scenes and composite them together - so each part you need to move separately create a separate scene for (with transparent backgrounds, which is the default), so you can superimpose all the scenes to make your final mash up.
