Benzyl acetate is neither an aldehyde nor a ketone. It is an ester, specifically the ester of benzyl alcohol and acetic acid.
The ester formed from benzyl alcohol and acetic acid is benzyl acetate.
To convert an aldehyde to a ketone, one can use a reducing agent such as a metal hydride (e.g. NaBH4) to add a hydrogen atom to the carbonyl group of the aldehyde, resulting in a ketone. This process is known as a reduction reaction.
From its structure, we can see that vanillin does not have a ketone functional group, but it has an aldehyde. It also has a phenol and ether functional group. For that reason, I wouldn't categorize is as just an aldehyde.
Cinnamaldehyde is an aldehyde. Its structure contains an aldehyde functional group (-CHO) attached to a benzene ring.
Ethyl methyl ketone can be prepared from calcium acetate by reacting it with barium hydroxide to form barium acetate, which can then be treated with sulfuric acid to yield ethyl methyl ketone. The ketone can be further purified by distillation.

An aldehyde (as the name says)
To convert an aldehyde to a ketone, one can use a reducing agent such as a metal hydride (e.g. NaBH4) to add a hydrogen atom to the carbonyl group of the aldehyde, resulting in a ketone. This process is known as a reduction reaction.
They have the same functional group.

Cinnamaldehyde is an aldehyde. Its structure contains an aldehyde functional group (-CHO) attached to a benzene ring.
An aldonization is the formation of an aldol - an aldehyde or ketone with a hydroxy group in the beta- position - usually from a correpsonding aldehyde.
Ethyl methyl ketone can be prepared from calcium acetate by reacting it with barium hydroxide to form barium acetate, which can then be treated with sulfuric acid to yield ethyl methyl ketone. The ketone can be further purified by distillation.
When alcohol is oxidized it becomes acetaldehyde, which is toxic. The acetaldehyde quickly become acetate, and then finally carbon dioxide and water.
Since it is "dione", it is a ketone, and there should be a comma between the 2 and 3 such as in 2,3-butanedione.
Diacetyl is a ketone. It has a structure with two carbonyl groups attached to a central carbon atom.
The conversion of a ketone to an aldehyde can be achieved by using a reducing agent such as sodium borohydride (NaBH4) or lithium aluminum hydride (LiAlH4) in a solvent like ethanol or tetrahydrofuran (THF). The reducing agent donates hydride ions to the ketone, breaking the carbon-oxygen double bond and forming an aldehyde.
