I can't reproduce your Libertinus problem but the sans serif and 
monospaced fonts just use the wrong names.

\definefontfamily [mainface] [rm] [Libertinus Serif]
\definefontfamily [mainface] [ss] [TeX Gyre Heros] [rscale=0.85]
\definefontfamily [mainface] [tt] [DejaVu Sans Mono] 
[features=none,rscale=0.85]
\definefontfamily [mainface] [mm] [Libertinus Math]

\setupbodyfont[mainface]

\starttext

\rm\tf Regular \it Italic \bf Bold \bi BoldItalic

\ss\tf Regular \it Italic \bf Bold \bi BoldItalic

\tt\tf Regular \it Italic \bf Bold \bi BoldItalic

\stoptext
