Hallo

Tingene = The things / Ting - Thing/stuff. The ending "ene" is the ending used for specified plural. Bordene - The tables, Stolene - The chairs. etc. 'Ting' in itself is a both unspecified singular and unspecified plural. Examples: Jeg har mange ting - I have a lot of things/stuff. Tingen som ligger på bordet - The thing that is lying on the table. 

1. While not wrong, it sounds forced. Try using: Jeg kjenner ingen som snakker norsk -Direct translation: I know no one that speaks Norwegian.

2. To see - å se; This can be a bit confusing so I'll list some examples of how to use this word. [å se - to see]  [jeg ser  - I see] [jeg ser på - I am watching] To explain it as well as I can without knowing the rules and the technical terms; Watching is to look at something, or to actively see it. We do not have a word for the verb which is to actively watching something. So we say: Jeg ser på - I am watching, though the direct translation would be; I seeing/looking at. "Jeg ser på Youtube - I looking/seeing at Youtube."

3. Å bruke - To use. Jeg bruker - I am using. Jeg bruke - is in its (infinitum?, that's what we call this category of conjugation in Norwegian) To use, to drink, to eat, to dig conjugation. If my point comes across. You would need to specify a time. Jeg bruker - I am using. Jeg brukte - I used. Jeg har brukt - I have used. You could say: Jeg liker å bruke - I like to use. But bruke cannot be used on its own as a verb.

It became quite the essay in the end, though I was hoping to keep it concise. I hope you find this helpful.
