Help Me Identify, No Idea What These Coins Are | Spanish

Your photos are not the greatest for clarity but the coins look very much like 16th century Spanish maravedis of Philip (Felipe) II. Take a look at this link:-

For the bottom one, here are the details (I don't see much on the others from your pictures) :

Year: 1556-1598
Region: Spain
Denomination: Blanca - 1/2 Maravedi
Ruler: Philip II
OBV: Crowned PHILIPPVS Monogram, patriarchal cross
REV: Castle With Three Towers C Mint Mark, patriarchal cross.
Diameter: 15.53
Weight: 1.40
Material: Copper
Mint: Cuenca (the cup on the right of the PVS monogram)

They are all of the same type, but maybe not from the same place (check out the writing near the PVS monogram, on the left and on the right)
