Identity Needed of Four Coin Images [solved]

Hello all,
Will someone please help identify these images on the four coins by name, and exactly what is their relationship to each other? The fourth coin, I believe, is actually King Alfonse XIII of Spain himself.
Thank you... Dan

It's almost impossible to give you the exact coin pages for the first three without the reverse (since that's where the denomination is indicated), but all of those coins bear the image of King Alfonso XIII of Spain (1886-1931), at different stages of his life. His father died before he was born, so he was king from birth.

Assuming the first three coins are 5 Pesetas:

The fourth coin is most likely this one:

Hello
These four portraits are on king Alfonso XIII.From child to adult.
This is the connection of these coins.
Regards

Thank you... it never entered my mind that they were all of Alfonso XIII but at different ages. After three quarters of a Century I think alzheimer's finally taking hold... lol

Again... Thanks Dan
