There is no universal answer to any of those questions since the results vary from chip to chip, motherboard to motherboard. Even the memory configuration, PSU, GPU and other components may have some influence over the outcome.
The biggest variable is the CPU. This is why you see overclocking called "luck of the draw" or "chip lottery" by many people. You never know until you try.

No one can answer that because each chip and configuration is unique. Generally you are pretty much guaranteed a 10% overclock, 20% is usually ok with some good tweaking, and 30% or more is just really lucky. So that puts it in the range of about 4.0 is a pretty sure thing, 4.2-4.3 is quite likely, and 4.5+ for the getting lucky range.
If it's stable and good and solid the OC shouldn't appreciably change the life of the CPU since you are probably going to replace it in under the time they generally last anyway.

Again, there is no answer to your first question: every chip is different - specially when overclocked. At stock speed with a reliable cooler, the chip will probably last 10+ years unless something else fails first and kills it. Overclocked, it can be anywhere from instant failure to 10+ years.
As far as cooling goes, the Devil chips should be able to do 4.3GHz with something modest like a 212EVO/X.

I already answered that question: probably 10+ years unless something else fails and kill it first.
Semiconductors hardly ever fail first when they are operating within their specifications.
As for temperatures, that depends on OC, luck-of-the-draw and multiple other factors. In general, the 212EVO yields core temperatures 12-15C lower than the stock Intel HSF.
So there isn't any difference between a cpu that has been working 100% of the time during 3 years and a cpu that has been working 20% of the time during 3 years?
So, which will be the temperature when overclocking to 3.4? 55ºC? 60ºC? 70ºC?

For the third time: as long as semiconductors remain within their specified operating parameters, they hardly ever fail. As long as motherboard components have decent airflow around them and the case itself has a decent fresh air intake rate, motherboards will last several years too regardless of load - as long as it is within their specs.
As for temperatures, again, for the third time, exact temperatures will vary on a chip-by-chip basis so nobody can give you exact numbers... specially when overclocking where there are ABSOLUTELY NO GUARANTEES WHATSOEVER.

That means: stick to the stock specs... keep the package temperature under 72C, keep all voltages and all clocks at their specified values, etc.
If you want to know what all those values and tons more are, Intel has 1000+ pages explaining all of it in painstaking details.
Otherwise, all you need to know is that if you surround your stock-running CPU with quality components, keep it cool and clean, and leave it at that, it will probably run for 10+ years.
