Top coin looks like a Piece of Eight (8R) from Seville.
Turn top coin 180 degrees for proper alignment (castles and lions).

The first one appears to be Philip IV, eight reales of Seville with Assayer "D" circa 1622 - 1625, most likely. You can see the King's ordinal as "IIII", denomination, mint mark, assayer, and the first three digits of the date "162x."
