Answer 1

I'm not aware of existing YAML multi-column TOC.
To achieve the desired result you could place CSS code below, inside your styles.css:

.reveal ul {
    display: flex;
    justify-content: space-evenly;  /* space-around */
}

Just for the record, one can put content in side by side columns.
Run again .qmd:

---
title: "Test"
author: "M Yaseen"
format:
  revealjs: 
    toc: true
    toc_float: true
    toc-depth: 2
    toc-location: body
    toc-title: "Contents"
    css: styles.css
