Oxalic acid is a non-polar molecule due to its molecular structure.
Phenyl salicylate is a very polar molecule. It has strong intermolecular hydrogen bonds, hydrogen bonded to oxygen I concur!! The hydroxyl (-OH) group that is on the salicylic acid part of the molecule allows strong hydrogen bonding to occur. It's lack of solubility in water though could be the result of a stronger attraction to itself than to being solvated by water.
Cysteine is a polar amino acid.
Tyrosine is a polar amino acid.
Lactic acid is a polar molecule. It contains both polar (-OH) and nonpolar (CH3) groups, but the presence of the polar -OH groups makes it an overall polar molecule.
No, cysteine is a polar amino acid.
salicylic acid (an acid) is more polar than methyl salicylate (an ester)

Salicylic acid is more polar than aspirin because it has a higher solubility in water due to the presence of a hydroxyl group that enhances its polarity. Aspirin, on the other hand, has an ester functional group, which reduces its overall polarity compared to salicylic acid.

Acetic acid (CH3COOH) has a polar molecule.
No, cysteine is a polar amino acid.
Detergent is both polar and non polar, it is able to collect the grease because of it having a non polar head. It also has a polar 'tail' which is why the globules of grease float about in the water.
Yes, tyrosine is a polar amino acid.
No, hydrochloric acid is not soluble in cyclohexane because cyclohexane is a nonpolar solvent and hydrochloric acid is a polar molecule. Polar and nonpolar substances do not readily dissolve in each other.
I assume you mean in water. Salicylate is a salt of salicylic acid. An organic salt is (pretty much) always more soluble in water than its non-salt counterpart. Water is polar, like dissolves like, etc.
