Words of Bravery is ally-unfriendly, but the flavor text says that you're only hitting the enemies around you. It seems like it should target "Each enemy in the burst".
I think the timing on Words of Ancestral Bravery works, but it's a bit confusing. Can the ally gain the benefit from ending its turn adjacent to the runepriest for the saving throws being made that turn? In an analogy, is it like Magic's end step starting or its end step ending?
Words of Celestial Heaven (the Enlightened Word daily 20) should have the charm keyword. Also, based on the rules of "end of turn" on page 198 of the RC (which I just looked up for the last one), creatures can't take actions during their end of turn, which is when the aftereffect would normally come up. This means that the aftereffect technically doesn't work, since it's a free action forced attack.
