Nagato was explicitly stated to have mastered all 5 natures by the age of 10. Not sure about Hagoromo, but I suppose it was stated too somewhere if it's there? Madara can use Fire Release. He can also use Wood Release and therefore its two components Water and Earth by extension. He was shown using Lightning Release before he grew a vagina and Wind Release in anime OVA.
