CONJUNCTION AS, WHEN, WHILE,

I'd like to know the exact meaning of conjunction as, when, and while. and how they are used.

In the following sentences, can 'as' be changed when or while?

-------------

He came up as I was speaking.

Just as he was speaking, there was a loud explosion.

He trembled as he spoke.

As we go up, the air grows colder.

--------------

I'd appreciate your help. ^^

All are correct, but I would caution the use of 'while' on the last sentence. It's not incorrect but it's probably not the best word to use here. I think it's because 'while' signifys two events happening at the same time but doesn't include the implication that one event is a consequence of the other, whereas 'as' and 'when' can have this implication.
