Since you are over age 59½ and it has been more than 5 years (the 5-year rule for qualification) since the beginning of the year for which you first contributed to a Roth IRA, *any* distributions you receive from your Roth IRAs will be qualified distributions, tax and penalty free, including those deriving from Roth conversions no matter when the Roth conversion took place. As I mentioned in #2 above, the 5-year rule for conversions (a different rule from the 5-year rule for qualification) does *not* apply since you are over age 59½. (I've edited that statement above to make it clearer.)
