They all need to begin with a capital letter, so none of them is correct.

I don't understand what you are trying to say. Please explain briefly what it is that you mean, and why you need to start with 'Yes.'

I am not a teacher.

If I understand you, "ask" is too general to set opposite to order, and the idiom is wrong. Perhaps you mean, "They will not request it, they will order it." (They have the authority to demand it rather than merely ask for it, and they will.)

 

[Khosro]

yes, they will not ask for it but order for it.

yes, they will not ask for it but will order for it

yes, they will not ask for it but they will order for it.

Guys, what about the omitted words in the first and second sentences?

 

[Raymott]

yes, they will not ask for it but order [STRIKE]for[/STRIKE] it.

yes, they will not ask for it but will order [STRIKE]for[/STRIKE] it

yes, they will not ask for it but they will order [STRIKE]for[/STRIKE] it.

First, it's "order it". You don't "order for" something. I don't like your choices, but all are possible.
I'd say, "They won't ask for it; they'll order it." (if I've read your intention correctly.

Thanks for your valuable suggestion and yes you have read my intention perfectly correct...
