Winged Dragon of Ra must be normal summoned. It doesn't actually matter about turns, just as long as you keep the 'one normal summon/set' per turn rule in mind. You could special summon all three and then tribute them to Tribute Summon Ra. But if you normal summoned the third monster, then you could not Tribute Summon Ra that turn unless you had a way of granting more Normal Summons, in which case yes, you could do it.
