Does anyone know who is in these photos? (Surnames: Panaretos, Trifilis, Mellitas)

Recently found some old photos from my dads trip to Kythera in 1960s/70s and wondering if anyone recognizes people in the pictures? In the top middle photo with priest my grand-uncle Pete is on the far right. The top right photo is of my grandmother Despina and my dad Nicholas (sunglasses) - man with hat is possibly named Tassos? Bottom right photo looks like my great-grandfather Theodore Panaretos (holding fishing pole).
