1. Where i can translate FB like term: Be the first of your friends to like this?
You can't. You don't need to translate. It is a iframe that is grabbed from Facebook. So, if a user is using his/her Facebook in a different language, then they will see this text in their own language.
2. What is problem if 'add to cart' not working?
i need to see your website to figure out. There are millions of reason for that. 99% of them are because jQuery Conflict (open the "Developer Console" and check for RED WARNING error. Check here for more info:

3. What i can change Enlarge Picture effect? For example - popup effect.
Asymmetric comes with 2 different product details page layout:
DEFAULT and FLEXV2
Default uses "Popup" to enlarge pictures. Live DEMO:
demo.flexiblewebdesign.com/asymmetric/index.php?option=com_virtuemart&view=productdetails&virtuemart_product_id=37&Itemid=162&lang=en
FlexV2 uses "Enlarge" to enlarge the picture. Live DEMO:
demo.flexiblewebdesign.com/asymmetric/index.php?option=com_virtuemart&view=productdetails&virtuemart_product_id=37&Itemid=162&lang=en
To change the layout for product details page, look at the TUTORIAL.PDF, it has been explained in there.
If you want to enable "popup" in FlexV2, (kind of mix the order) then you can't do that. Because they are designed that way. It will require coding changes, which is not covered by free-support.
4. Why product tabs (product description, Review, Ask question) not working?
It is related to your 2nd inquiry. Once the jQuery conflict is resolved, everything will start working fine.
Avoid installing 3rd party extension to your website, or install with caution. They are most likely tend to causes jQuery conflict issues.
