拜托请问such~as跟such as 和 the same as/that后面接的名词问题

拜托请问such~as跟such as 和 the same as/that后面接的名词问题
1.such~as 那样的~
I have never seen such a man as he is.
这句话为什麼有些人那个man可以用复数men?
ex:Such men as he are rare now.
是单复数都可以用麼?
还有such后面可否使用不可数名词例如 bread money tea等等?
2.such as诸如
这个片语我想问的事情是
后面所接的名词要单数还是复复比较好?
例如such as a egg/such as eggs?
3.the same as/that
这个也是差不多烦恼
所接的名词已知单数
那麼复数或者是不可数名词也可以麼?
ex...自己用的例题文法
These are the same books as I bought yesterday.
This is the same bread as I bought yesterday.
These are the same books that I lost yesterday.
This is the same bread that I lost yesterday.
