4. What does the Bitcoin mining represents by itself?

Bitcoin Foundation issues the reward for the usage of user’s computing power.
All Bitcoins were created beforehand and are distributed between the users in strong proportion with their contribution to the network computing power.
Bitcoins are created by the mining companies
Bitcoins are awarded as a reward for decoding of transacted units, and their replenishment.

5. Would the miners disappear when number of the mined Bitcoins lead to 21 million?

Yes, because they would not be able to get a reward
No, because system would go to another level, and new issue company would start
No, because the transaction calculation is always required, reward would be calculated out of the increased commission per transaction
Yes, because the Bitcoin would no longer exist, if all Bitcoins would be mined.

6. What is the protocol for financial transactions among the following services?

Ripple
Armory
Friendly pay
Сryptorush

7. Is there a difference in graphic card performance when Bitcoin and Litecoin are mined, and why?

Yes, because of the complexity differences
No
Depends on the transaction approval speed
Yes, because of different algorithms

8. Could the Bitcoins be stolen?

No, because this is just a programming code
Yes, as well as any other digital docs or data
No, because there is a need to perform the block decoding process again
Yes, but only by the phishing way (tricking to transfer Bitcoins from purse to purse)
