Thinking out side of the box, is EVERYTHING possible in math? Such as 6=-9,348,393,423,842,340,983,202,934,029,384,092,834. is it possible for 2 to equal 9?
Please Explain

NO, your theory is flawed 2 has to equal 2 and it cannot equal 9. If you assign 9 the value of 2 then 1 = 8, 0 = 7, -1 = 6, and so on. You are just changing the values and you might as well say that 2 = B, 3 = C, 4= D and so on.
However 2 + 2 = 5 for sufficiently large values of 2.
Another worlds 2.5 + 2.5 = 5. 2.5 is a sufficiently large value of 2, but 2.5 is still 2.5 it is not 2 nor anything else.
The entire idea of math is that you set forth a statement, called a postulate, and then try to prove it. If you can then that postulate is true and you can use it in more advanced work. The hardest postulates to set are the most basic ones. When my high school Geometry teacher got tired of people complaining about doing Geometric Proofs she said, "Be glad that I am not asking you to prove that 1+1 = 2." To this day I am not sure how to prove it without relying on other mathematical concepts.

A postulate is something that is accepted to be true without the need for proof. There is no proof that 1 + 1 = 2. All of the harder maths are based on a few postulates.
Postulates can't be proven. They are ideas that you have to live with.

No. 2 is never equal to 9. See "1984" by George Orwell.

no it is not.Because 2 is an even number but 9 is an odd number.

it depends on your main system, for example in Pythagorasian geometry sum of a triangle is exactly 180d but in non-Pythagorasian if you draw a triangle on a sphere sum of its angle would be more than 180d
