whats more mechanically sympathetic ?

so going in fourth gear at 4000 rpm is better than going at 3000 rpm in fifth where the acceleration is extremely slow or zero? I thought high-revs are what kills the engine, I never really go past 4000 rpm on my car ever unless I need it.
Grannying it everywhere isn't good for it either.A mixture is. Nothing wrong with using the full rev range once it's warm.
Under the conditions you've described, I would expect a downshift to 4th to be needed in a 1.2 Corsa.
You could hold out it top, it may manage to build the speed, but back to your question it would be easier on the engine to drop a gear.
4000RPM is not particularly 'high' revs for a petrol engine car, you won't hurt it at these revs all day long. Holding your engine on the limiter for long periods of time probably will!

I dont know whats right, high revs make the car cry, high gear low revs feel like engine is working too hard
High revs = no problem, that's why you have a limiter 
Peak power is what you need to aim for which is probably around 4500rpm 
Obviously there is a balance to it and bouncing it off the red line routinely is stupid/pointless and you're off the power anyway. Just keep dropping it down until it pulls harder and as said, it'll "feel" right.

If when you put your foot on the accelerator pedal it won't accelerate(assuming you've not run out of revs) you need to change down. Your car will have a limiter to stop the engine flying to bits of you over rev it. It might not be the most refined engine you could buy it might sound harsh at high revs as long as it gets serviced it won't come to any harm. IIRC to get type approval to be sold in Europe your car has to be capable of running flat out because people can and do drive them flat out in Germany.
Giving it a good work out won't hurt it one bit.

Depends.
How long do they sit on engine dynos in testing just banging off the limiter? (Although they do have decent coolant flow)
True, I know the makers usually bench test an engine like this to ensure durability, but I'm assuming this Corsa isn't new and may have a few thousand on the clock. Hitting the limiter occasionally will be harmless. ETA for a healthy engine!How long do they sit on engine dynos in testing just banging off the limiter? (Although they do have decent coolant flow)
suppose I want to accelerate on an incline from 60mph to 70mph, the car is full with five people (including driver) and I am in fifth gear. what puts that less load/strain on the engine:
its a corsa C 1.2L I am driving.
I doubt if a Corsa 1.2 could make it up an incline with five people in.
Btw you should never labour a car in any gear, especially on an incline, have you passed your test?
