-----------------------------------
Are they all grammatical? Is #2 right?
What are the differences in meaning?
Does #1-1 mean #1-2? What is the meaning of 'while' in #4? Although, or however? Does #5 mean #6? What is the difference between them?

Answer 1

Sentences 1 and 3 mean the same thing, and 2 and 4 are close.

Sentences 5 and 6 make me wonder -- were you reading and walking at the same time? "While" indicates simultaneous actions.

Answer 2

1-1. When I entered the room, she played the piano.

1-2. As soon as I entered the room, she was playing the piano.

<u>These sound as if she started to play the piano when you entered the room, not that she was already playing and then you walked into the room.
