Galaxy S5 how do I add Public and School Holidays to S Planner

Since each school has a different set of "holidays" (other than the normal ones everyone even not schools celebrates), I'd say manually, one at a time, every year. If S Planner is linked to your Google Calendar (I don't have S Planner), go there, go to Other Calendars (on the left) and add the Holidays calendar.
