Fixed width, minimum width and maximum minimum unsigned minimum width 8-bit integer

Question

Three days later I read an article about the choicecorrect integer size . Before reading this article, I did not know about these three keywords:

1) 8-bit integer with a fixed width unsigned uint8_t. (Typedef - C99 complaints)

2) The minimum width of the unsigned 8-bit integer: uint_least8_t.

3) High minimum width of the unsigned 8-bit integer: uint_fast8_t.

So my question is:

1) What exactly do they mean by saying "at least 8 bits wide" for uint_least8_tand uint_fast8_t. For example, let's take a look at a piece of code

for(u16 i=0;i<counter;i++)
{
  Increment_Counter++;
}

Here: - u16 means unsigned short. counter and Increment_Counter are two variables

counter =0xFF; Increment_Counter . , counter =0x01FF; ? uint_least8_t ( 8 ) unit16

2) uint_fast8_t .

3) uint_least8_t , unsigned char.
