The boys across the back row, left to right are nicknamed as follows on my blog:
A guy who doesn't have a nickname but the boys always tell me, "Black, Amanda, Black!", Powerful, Cocky Guy, Brave, Studious and Tired Guy.
The boys in the front row are mostly nicknameless, but the one on the far right is Ghost-Little Brother. Photo taken 30 October 2006 in South Korea.
