The red words in the OP are possessives. You can use my, your, her, his, its, our, or their. Depending on the grammar of the context you could also use a possessive pronoun: 'It's no concern of mine/yours...' etc.
If I'd met it, I'd think it meant 'interfere'. But I tend to hear the 'pie' metaphor used chiefly in a descriptive way: "There are lots of people with fingers in that pie" [='lots of people are involved/have an interest in it']. I wouldn't mention "pie" at all if I wanted to say 'Don't interfere'. I'd say something like 'Mind your own business' or 'Keep your nose out [of other people's business]'.

Hy. how do i know when i /[DO I]have to use "does it mean" or simply "means"? Thank you!
Also is the red variant correct or the first one? I believe it is when do I have to.. because it's a question but I am not sure. Thx again!
