The only reason I suggested “holy figures” is because this is the translation already used in the program of studies.

It could also be “Saints and Saintly Figures”

or "Saints and Venerable Figures"

So let’s please be clear: Όσιος is not less saintly or holy than a saint. And “holy” does not point to monasticism. “Venerable” would be more helpful in that respect:
In the Orthodox Church the term "Venerable" is commonly used as the English-language translation of the title given to monastic saints (Greek: Hosios)

όσιος and άγιος Let’s make sure we know the correct difference between όσιος and άγιος:
In the Eastern Orthodox Church, the title Ὅσιος, Hosios (f. Ὁσία Hosia) is also used. This is a title attributed to saints who had lived a monastic or eremitic life, and it is equal to the more usual title of "Saint".
https://en.wikipedia.org/wiki/Saint#Eastern_Orthodoxy

Το Ορθόδοξο αγιολόγιο της Εκκλησίας με τον όρο «Όσιοι» δεν κάνει κάποια διάκριση μεταξύ της αξίας (δεν μπορεί κάποιος να είναι περισσότερο ή λιγότερο άγιος) των Αγίων αλλά δείχνει ότι οι συγκεκριμένοι Άγιοι ήταν μοναχοί ή ασκητές.

Όσιος is translated as "Saint" as a noun and "saintly" or "holy" or "venerable"as an adjective. For example, Οσία Μαρία της Αιγύπτου will also be found as Αγία Μαρία της Αιγύπτου and in English is “Saint Mary of Egypt”.
