I can not understand when SIunitx places a point between units. in the examples below, why is there no point between \ kilogram and \ meter ^ 2 whereas there is one between \ newton and \ meter?

How to homogenize the writing of units?

PS: I also find that the space between the point and the units is too important, how to reduce it?

The siunitx package works in two 'modes': one where all units are given as macros, and the second when there is literal material in the unit. In the latter case, formatting is extremely limited: it's simply not possible to do the kind of processing that is doable with macro-based units. When you add ^2 rather than \squared, you are forcing 'literal mode' and the package cannot add inter-unit information.
