Are sharingan users like Itachi, Madara, Obito, and Sasuke immune to all genjutsu, or only the ones that affect sight? Say someone developed a genjutsu that made the opponent (Itachi, ext) feel as if they were on fire (Sense of Touch), like a scream was piercing their ear drums (Sense of Hearing), or like their tongue was tasting something extremely sour or smelling something bad (Sense of Taste and Smell). Does having an advanced sharingan make you immune to genjutsu affecting any of the 5 senses, or only just Sense of Sight?

No

and genjutsu usually affects all five senses. However there are different options for applying genjutsu. sound based genjutsu work on Sharingan users.
