"If space is created by just local presence of matter, then there should be little space where there is little matter, is this correct?"

Well kinda of, but matter is everywhere, known as dark matter, quantum vacuum energy, the Cassimir effect.

"Also, if extra spatial dimensions are big, they are different than the spatial dimensions we already know, othervise we would call our space 4, 5, etc.- dimensional. Therefore, can we call those DIFFERENT dimensions (like 4th space dimension bent by gravity) indeed to be equal space dimensions? We have to assume then that some objects (gravitons) CAN exist in higher dimensions, but some other (protons) CAN NOT. "

I believe I stated that the extra spatial dimension is virtual or equal to zero.

"For example dig two holes - one on Earth, one on Mars, then take a coin and ask you friend to plant it EITHER in Earth OR in Mars hole, and without telling you in which one. Also ask him to disappear from anybody's sight, so noone can guess where the coin might be hidden."

Problem here: One the analogy should be two coins, one reads heads the other reads tails and always one is the opposite of the other.

Two: The measurement or check should be done simultaneously, so there is no way a secret code can be established to fool anyone.

So with a consistency of readings the only way to connect the two coins would be through an extra dimension.
