No they don't

Only those minerals are put in silicate group which have $Si$ (silicon) and oxygen combined in their chemical formula. For example

$SiO_2 ->$ Quartz

$Fe_2SiO_3$

$Mg_2SiO_3 ->$ (Olivine)

Carbonate have carbon and oxygen. For example $CaCO_3$ (calcium carbonate)

Halides have combination of salt forming elements of 7th group ( $F$ , $Cl$ , $Br$ , $I$ ) with other elements. For example $CaF_2$ , $NaCl$ etc

Sulfides have $S$ (sulfur) with other elements like $ZnS$ , $PbS$

Conclusion
Only Silicates have silicon.

hope this helps thanks
