The first one is Chloe Munton, was with Boss Models South Africa, couldn't find any other agencies, her IG page is private. Google gives a few results including a YouTube video. I found her through the photographer, Jacob Lund (found him from a Yandex search) - #jacoblundphotography and a comment on one of the posts was a makeup artist who had her full name and an old IG page but the photo was tagged with her current (private) IG page.
