If you mean the hydroxyl functional group (-OH), then only serine and threonine contain it. However, all amino acids contain one or more carboxylic acid (-COOH) functional groups and they all contain OH as part of that functional group, though the carboxylic acid functional group should be considered a single unit.
carboxylic acids
Not necessarily. Alcohols have -OH as functional group.
Yes all amino acids contain an amino group which contains nitrogen ---> -NH2 hence the name amino acid. This is a common group in all amno acids, it is only changes in the R group that leads to approximately 20 different naturally occurring amino acids in humans.
Functional groups are responsible for chemical reactions of molecules.

Phosphate group.
Functional Group
Formaldehyde, as its name implies, is an aldehyde. Thus, it contains a carbonyl (CHO) functional group. This group consists of a carbon atom double bonded to an oxygen atom. The carbonyl group is the only functional group contained in formaldehyde.
Not necessarily. Alcohols have -OH as functional group.
carboxylic
Alcohols are a substituted hydrocarbon which contain the hydroxyl (OH) group.
carboxylic acid
This is the group amine.
alkane haloalkane amide alcohol ketone not so much a functional group but it does contain ring structures like benzene
