1) Has there been any mention of hijab in jannah? I ask about hijab because i’ve read about people meeting and greeting each other. Men and women so will there be any form of hijab rules that have been mentioned in the afterlife?

2) And how does a soul look like. Is it completely like our human body or something else.

Our hadiths don’t mention Hijab in heaven. So we don’t know.

As for the soul, most scholars believe it’s a very thin material, but it has physical dimensions. We don’t know what the essence of the soul is. You can see this for more info:
