In the Second Wave scenario, where exactly can a power from the first wave be used? What if the power is targeted from a Sacred Site? What about (one of many weird exception cases)?

The power can target any land or Spirit it normally could - no current Spirit needs to have a Sacred Site (or Presence in a land of the correct terrain, etc.) The power is being "played" by the Spirit from the prior game - if it cares about the originating land, or where the Spirit has Presence / Sacred Sites, it can assume that for purposes of targeting and resolution the Spirit has up to 2 Presence in each land. The Power can't affect the playing Spirit (which is not in the game). Technically, Energy/other costs can't be paid, but it's more fun if you say that costs up to 8 Energy / 4 Time, can be paid. (Or rough equivalent, so Elemental Teachings can grant 3 of any element(s), Draw Towards a Consuming Void could redo its effects once, etc).
Along similar lines, it would be thematically appropriate to apply most sorts of Special Rules for the Spirit "using" the Power, but creating a precise formal specification for exactly what should/shouldn't be considered would get very finicky. Use your judgment.
