Strong pain on the upper right front. Is this the liver area?

Yes, and gallbladder. The liver is in the upper right abdomen, but so is the gallbladder. It is more common to have pain from gallbladder issues than liver issues. Gallbladder pain usually starts suddenly, is very severe then may slowly go away. If the pain is severe, you should get this checked by a doctor.
Quite possibly. Direct injury to the liver, by itself does not produce pain. However, the liver (and the other abdominal contents) can irritate the body wall which can perceive pain. The best thing to do is to seek medical attention. In the setting where you can show a clinician where it hurts, when and how, and he/she can look at it, you will obtain a more definitive answer.
