There exist "stable" exotic particles of that have non ordinary amounts of lower level quarks. https://www.symmetrymagazine.org/article/lhcb-discovers-long...

Maybe they might have non integer charge.

In QCD, they cannot. All Feynman diagram vertices involved in producing these things (in fact all QCD vertices period) only deal in integer charge units and never leave fractional charges floating around.

Ok, I see. Also pentaquarks all have integer charge.
