I want the font size of a whole document to be 14pt or 16pt. Or I noticed, that for 10pt, 11pt or 12pt, everything is fine. For all other font sizes, the document is written in 10pt font size. Is there a way to change that? I am using TexStudio (does it change something? I doubt it).

For example, the code here (with 16pt asked) gets a 10pt font size:

\documentclass[16pt,a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[french]{babel}
\author{R. Pereboom}
\begin{document}
    Some text
\end{document}

I get the same result with any font size except 10, 11 or 12pt. For instance, 8pt is not working either. I hope I am explicit enough...

The standard classes only support 10pt, 11pt and 12pt.

You can use the fontsize package that does a good work in guessing the relative sizes. For Computer Modern you need also fix-cm.

\documentclass[a4paper]{article}
%\usepackage[utf8]{inputenc} % no longer needed
\usepackage[T1]{fontenc}
\usepackage[french]{babel}
\usepackage{fix-cm}
\usepackage[fontsize=16pt]{fontsize}

\begin{document}


Some text


{\small Some small text\par}


{\footnotesize Some footnote size text\par}


\end{document}

If 17pt is a close-enough substitute for 16pt for you, I suggest you replace

\documentclass[16pt,a4paper]{article} % '16pt' not a valid option

with

\documentclass[17pt,a4paper]{extarticle}

The extarticle, extreport, and extbook classes are just like article, report, and book, except that they recognize 8pt, 9pt, 14pt, 17pt, and 20pt as additional font size options. Of course, the basic 10pt, 11pt, and 12pt options continue to work too.

The memoir class (which can be used to typeset documents in the style of book, report and article classes) provides type size options 9pt, 10pt, 11pt, 12pt, 14pt, 17pt, 20pt, 25pt, 30pt, 36pt, 48pt and 60pt, plus an author-defined type size. Within a document, depending on the type size option, you can use fonts ranging from 4pt to 132pt. See the manual texdoc memoir section 3.2 for more information.

These are close to, but do not exactly match, those provided by traditional lead type. From www.arionpress.com/mandh-pricelist-ordering they can provide lead type in the following pt sizes:

6, 7, 8, 9, 10, 11, 12, 13, 14, 16, 18, 20, 22, 24, 30, 36, 42, 48, 60, 72, 84

In LaTeX be carefull about using fonts other than Knuth's. Ideally the shape of each font size should be different. A font designed at 25pt will differ, perhaps significantly, from a 10pt scaled up to 25pt. Font scaling is not linear --- different parts of a character may need to be treated differently. Perhaps horizontal lines made thicker and verticals made thinner, or maybe the other way around.
