Yes, unless specifically described as bounded.
Geometric space is three dimensional and infinitely large.
In our real world, the space is 3D. It is currently unknown whether it is infinitely large.

Infinitely many.

A geometric surface is a mathematical representation of a two-dimensional shape that extends infinitely in two directions. It can be defined by equations or parameters in space, and is often used in geometry, computer graphics, and engineering to model objects and analyze their properties. Geometric surfaces can include simple shapes like planes and spheres, as well as more complex forms like curves and manifolds.
Geometric Space
It is a plane.
Because the universe is neither infinitely large nor infinitely old. If you need more details, look up "Olbers' paradox".
