An independent director has no business or family tie to the company, its promoters or its managers beyond the seat. Listed boards counts the boards of listed companies the director sits on, this one included, and "as independent" how many of those seats are independent ones. Committee seats are audit and stakeholder committee seats across those companies. Months as independent is filed for independent directors only, whose terms the rules cap. Disqualified is the company's own mark that a director may not serve under company law.
