'He's stood in front of me, facing away from me' 'He's stood in front of me, with his back turned'

"standing in front of me" does not imply if the person's back is turned, it simply means that they are positioned in front of you. face to face would imply eye to eye contact

there are five ways of saying placement around an object (like yourself) 1)in front 2)to the left 3)to the right 4)behind 5) to the side (to the wayside) (left or right isn't given) There is no indication that the object being around the main object is faced or positioned in any other way without further information. So, to say, "He sat down in front of me" could indicate both sitting facing forward or sitting facing the main object. "That little girl kept running in front of me, which made me spill my tea!" shows that the object doesn't even need to be stationary. "To the side" would work in situations where it wouldn't matter where it went. For instance "When I ran for the door I pushed him to the side". I know I talked about more than asked, but I thought it was relevant information for you. Good luck.

Yes, "in front of me" can describe somone standing ahead of you in line.
