1 - 他对着: he facing towards; 着(zhe) after a verb indicates an action is in a progress or in a certain state that continues (I think it's like using -ing in English); 对(dui4) prep means “to, at, towards“; 镜子 (jing4 zi5) is “mirror“ 整理 (zheng3 li3) to arrange, to comb (this meaning is not from dictionary but apparently from the context in this sentence it means “to arrange, to comb“

1 - 个体面向：他面对着（着，动词之后用以表示动作正在进行或处于某种持续状态， akin to the use of -ing in English）；对，介词，意为‘向，在，朝向’；镜子（镜，子），意为‘镜’；整理（整，理），意为‘编排，梳理’，此意义非词典定义，但根据句中语境，似指‘编排，梳理’。
