这里的boy students表示的是男生,复数体现在students上,boy是修饰students的.而men teachers、women teachers是特殊用法.

boy
男学生 是boy student ， 复数boy students
a man teacher 复数 men teachers 这是特殊的

a lot of 后边跟单数
many后跟复数

是 we have many male teachers
Male and boy 都是形容词描写性别的，所以不可以是双数

道理很简单：英美人的习惯。他们不说boys students，只说boy students。这些表达习惯是无法用一般的语法解释的，只能靠你自己强记。
