Ancient copper coins found in foreign junk bin

[Pennysaved]

I went through the foreign junk bin and found some copper coins that look pretty old

1st one:

hard to make out because of wear
Obverse: HTLIPR D G REX VJKI I can make out an 80 as part of the date portrait of face facing right
Reverse: see some stocks of wheat and MODITAT

2nd coin:
Obverse: IPP some other letters i cant make out and a face and shoulders facing left
REVERSE: either a ram or a donkey that appears to be carrying a load

3rd coin is really worn
Obverse: appears an obese man portrait facing right
Reverse: circle with an X on one side and a rectangle on the other side and a crown above the circle only letters I can make out are a T H I R

Any easy way to idenfity these?

I think the 1st coin is a Phillip II of Spain
