Hi I want to change my standard font of my overleaf testfile..
The example is strange because I need to write a custom comand before my code.
But I just want to use my ttf as standard everywhere!

% Example of how to use a custom TTF font by following the directions here:

Answer 1

I suggest to compile your document with xelatex or lualatex. This way, you can use the fontspec package and easily use fonts installed on your computer or even just .ttf files:
% !TeX TS-program = xelatex
\documentclass{article}
\usepackage[english]{babel}
%\usepackage[utf8x]{inputenc} % don't use `utf8x`
%\newcommand\customfont[1]{{\usefont{T1}{custom}{m}{n} #1 }}
\usepackage{fontspec}
\setmainfont{lokisd__.ttf}
\title{Example: Custom Font}
\author{writeLaTeX}
\begin{document}
\maketitle
Normal Font Text.
\Huge Custom Font Text!
\end{document}
