Is it okay if / to ///// Is it possible to / would it be possilble to ///// would it be okay//all right if -

I'm wondering that these meanings are all the same?

I'd like to know the delicate deferences among them.

Is it okay if / to

Is it possible to /

would it be okay/all right if -

would it be possilble to

for example

1. Is it okay if I take your breath away?

2. Is it all right if I take your breath away?

3. Is it okay to take your breath away?

4. is it possible to take your breath away?

5. is it possible for me to take your breath away?

5. would it be okay if I took your breath away?

6. would it be all right if I took your breath away?

7. would it be possible to take your breath away?

which one do you think most common and sounds better?

could you just pick one the most common pattern?

ps) is it possible to say like "Would it be possible if - - -?"

ex) Would it be possible if we did not say "good-bye" this time?

It has been bugging me. If you know the answer, I really appreciate that:D
