What's the shelf life on one of these fuel canisters unopened, and how long do they last after they have been half used? Do they leak?

Although it wasn't this brand, I used mine a few times on 4/1998, stored it with my hiking equipment until I used it again and emptied it this weekend, 12/2019. Worked fine.

The cap is always on the cylinder, i want to see it without to see if it looks like a gaz canister?

A lot of people don't pay attention and assume they know what they are talking about. They are self absorbed morons. These won't fit "gaz" attachments. I have a gaz stove and lantern and can't find canisters either. This stove is threaded just like an MSR canister. I would also mention that iso-butane mixes are much better than the straight butane mix. There is a difference.

Will this work on jetboil?

I went camping w a number of guys w jet boil burners who used generic containers like this. I’m not 100% sure it will work, but 95% sure it will.

Why are these 120‰ more than Retail?

Shipping. They are hazardous materials, so it's much more expensive to ship them than to ship non-dangerous items. Buy locally if you can. Any store with a decent selection of camping gear will have similar cylinders. The MSR and Jetboil brands are the most common in the US. If you must have your camping fuel delivered, these are about as good a deal as you will find. These are the small 4 ounce (approximately) cylinders that are designed to fit inside some camp stoves for storage; the larger 8 and 16 ounce cylinders are a better buy per ounce of fuel.
