Answer 1

Hi

The best equivalent for "عمرا" is "not on your life".

not on your life => (informal) used as a very forceful way of saying "no" or "never" 

(Merriam Websters advanced learners dic).

example: Do the government's policies really help the average worker? Not on your life

(websters).

Three more equivalents:

1. No way

example: Me join the army? No way! (NTC's Slang and Colloquial Expressions).

2. Never

3. Never ever

 

Answer 2

some hope! (what a hope!) spoken (=used humorously to say that there is no chance that something will happen) ‘Your dad might lend you the car.’ ‘Some hope!’

perish the thought!
 

you should be so lucky!
