So we see souls having their own particular physics in the manga. Of course, edo tensei works by binding the souls with a living sacrifice and dust particles. Rinnegan has the ability to rip out souls, thus killing the target, or using Rinnetensei to restore the body of a target and then return their soul. Also, the Gedou Mazou has the ability to devour souls with its dragon shaped chakra appendage in its mouth. On top of this, Dan had a jutsu allowing him to move freely as a ghost in the physical world, though temporarily. We even saw Obito, as a spirit, still have access to the genjutsu he had while living.
However, you also have the tailed beasts which are simply chakra giving physical form, do they also have souls? What is the relation to a soul and a person's chakra? We know that edo tenseis, which is the souls of the deceased inhabiting someone else's fresh corpse, are free to use the techniques and chakra of the person who's soul is bound to it. So are souls chakra? Or are they different but are used in the process of chakra generation? And with Obito's spirit having Kamui in the after life, perhaps your soul has all the abilities you had prior to death or its extraction. This would explain how edo-tenseis can use their dojutsu despite their original physical eyes having been destroyed or planted into someone else, as was the case with Madara's Rinnegan.
However, when Madara's edo-tensei was given life through Rinnetensei, his "fake" Rinnegan crumbled away, so it seems that even though his soul retained the dojutsu he had awakened while living, having his body restored still could not restore the eyes he lost while alive.
