On (4), to do that you will need either my Zone Based Shipping addon (variable fees per zone calculated from cart content) http://www.concrete5.org/marketplace/addons/zone-based-shipping/...

or Mainio's Regional Shipping addon (fixed fees per zone)

First of all, I would like to point out that seems like your requirements are so big that it would probably be better to do it with alternative platform. You will need probably have at least some level of limitations with eCommerce.

But everything is possible, here are the answers:

1/ Does the transactional emails are activated and customizable?
>> Yes, like any email in c5.

2/ Can we define a currency for each country ?
>> Yes but this is really limited, it just auto-selects the currency based on the language version. So you will basically need to have own products for each country/language/currency.

3/ Can we define sales tax for each country (19,6% ; 5,5% ; etc..) and by zone ?
>> Yes.

4/ Can we define shipping fees for each country and by zone ?
>> Yes, as John replied above.

Thank you guys :)

So for (2), We can't have a different price for each country, right ?

No, you'll need to have separate products for each country if you want different prices for them.

Otherwise it will be, e.g. for product that has price 10:
- 10€
- $10
- 10£
- 10$ (AUD)
- etc.

Thank you Antti :)
