I was wondering if vinegar and garlic, milk of magnesia, sand, and glue are: element, compound, homogenous mixture, or heterogenous mixture

Among the given components none of them is an element. A brief classification can be done as follows: Vinegar is a dilute solution of acetic acid in water; a homogeneous mixture.
Garlic is a mixture of organic compounds and tissues etc.; a heterogeneous mixture.
Milk of magnesia is a suspension of magnesium hydroxide in water; a heterogeneous mixture.
Sand is silicon dioxide or silica; a compound, when pure. But it forms a heterogeneous mixture when mixed with other substances, soil, salt etc.
Glue is a synthetic (or natural) compound dissolved in a suitable solvent or, a mixture of two compounds that react to form new bonds; either way it is a homogeneous mixture.
