These portraits come from Atrium Heroicum Caesarum c. 1600 by Dominicus Custos. The 100-odd copper engravings of royalty, nobility and elite troops from all over Europe were made from paintings. The subjects lived in the 15th and 16th centuries.
With respect to the names above that were crunched by translation and are probably a little wrong ... as the website says..
"We ask the bent reader for indulgence and if necessary for friendly report!"

Atrium Heroicum Caesarum is hosted by the University of Mannheim. (translation)
