Five year rule on IRA conversions to Roth for Older Folks

My dad who is 70+ has money that he incrementally converted from a Traditional IRA into a Roth IRA account starting over 5 years ago, showing the amounts as income each year.  Some of the funds were converted over 5 years ago some less than 5 years ago.  Since he is over 59.5 years old does the 5 year rule on converted funds apply or can the entire account balance be removed from the Roth without penalty or tax?
