Since yesterday, my question was incorrect, rephrase it.
1. Physical 1,000,000,000-dimensional space: it can be?
2. How can we imagine?
3.What kinds of matter and the interactions can there be?
Thank you.

Your English is very poor.

What reasons do we have to suppose that many dimensions?

Maybe he wants to know if a 10^9 dimensional space would "work" physically. Now, the answer is simple, if we think of a cellular automaton, any amount of dimensions is possible in which the universe would never freeze.
Now the real question is, do/can cellular automata accurately represent a physical reality?

OP learn about vector spaces/linear algebra

>1. Physical 1,000,000,000-dimensional space: it can be?
It can be what?

>2. How can we imagine?
You can't. You can't even imagine 4 spacial dimensions (fuck off Jacob Barnett), so there's literally zero way for you to imagine such a space.
3.What kinds of matter and the interactions can there be?
The same kinds. But there is way more freedom than in 3D space, so the likelihood of an interaction occurring is a lot smaller.

The question is based on a common confusion. The physical world can be entirely represented by 3 axes at right angles to each other. No other such axes are required or possible. The world is therefore 3 dimensional. Now, it is common that whenever you make a measurement you refer to the units as 'dimensions'. You can call 'peanut butter density' a dimension if you want -- but it means something else entirely. It's semantics, that's all, so you can answer your question in any way that pleases you and you can consider yourself correct. BTW: time is not a physical dimension, so don't start.

It would help to know what you're talking about before you post:

And mathematical spaces of arbitrarily many dimensions are not only possible but commonly used; they just don't correspond to real-world geometry. And this has nothing to do with dimensional analysis.
