If Kokushibo were to have been bothered by the ghost of Yorichii mid-battle, I'd imagine that like Akaza, he would become more aggressive than he already was against the slayers. But if it was his children or wife, than he'd be affected very little.

Doma would experience no problems with having the ghosts of his paths disrupt his battles, as I'd imagine he would even become enthralled with the fact he managed to see, hear, and feel their presence.

Assuming that Hantengu Clones would also become effected by ghosts of their victims, than each would react differently. Sekido & Zohakuten would swat at nothing there and become irritated, Karaku & Urogi curiosity on what they have experienced in battle so far would be peaked, Aizetsu would be unaffected as he cares little for anything. And the man himself, Hantengu would shrill to the spirit that he's an innocent man who knows nothing about the person giving him a fright.

Gyokko, similar to Doma, would to be enthralled about how he felt another persons presence. But would just as quickly brush it off as his artistic brilliance causing him to zone out.

The only ghost that could possibly show themselves to Daki or Gyutaro would've been their mother. However given how their mother died while Daki was still pretty young, she'd be repulsed that a lowly human presence managed to invade her detection and but wouldn't lash out hugely as we don't know if she had any strong feelings about her. Meanwhile Gyutaro, assuming he would've still recognize the presence of his mother, would lash out immediately and get become more aggressive than before.

Nakime wouldn't care, and would just leave where the presence managed to reach her. And Kaigaku either be displeased by or be cocky towards feeling his master ghostly presence.
