Not "Most my friends live nearby." — say "Most of my friends live nearby.". the / my / these 前面要加 of：most of my friends。
试一试: ___ my friends live nearby. (Most of / Most / The most) 答案: Most of — 后面跟着一个特定的群体（my friends），所以要用 of：Most of my friends。如果没有 "my / the / these"，泛指朋友时就只说 "Most friends"。
the most，说最...的那个

试一试: She is ___ talented player on the team. (the most / most / most of) 答案: the most — 这句话说的是她排第一，所以用 the most talented。"Most" 单独用是泛指人，"most of" 后面要跟一个特定的群体，不能跟形容词。
