There's no way to remove 'Videos' and 'Random page' &mdash; anything in the first navigation menu ("ამ ვიკიში" / "On the Wiki") can't be edited.

For the parts of the wiki navigation that are still in English, I'm not sure how translating them works. I'd recommend asking Wikia staff at Special:Contact if you can get it translated into your language.
