An acyl anhydride is a class of organic compounds with two acyl groups bonded to the same oxygen atom, which react with water to give carboxylic acids.
An acid anhydride is an organic compound that has two acyl groups bound to the same oxygen atom. Usually, the acyl groups come from the same caboxylic acid, he formula for the anhydride being (RC(O))2O + H2O
Acetic anhydride undergoes hydrolysis in the presence of water to form acetic acid and a byproduct, typically a carboxylic acid or alcohol. The reaction is a typical nucleophilic acyl substitution reaction, where water acts as a nucleophile attacking the acetic anhydride to break the anhydride bond and form acetic acid.

An acyl fluoride is a compound derived from a carboxylic acid where the hydroxyl group has been replaced with a fluoride atom. It is a reactive and highly electrophilic compound commonly used in organic synthesis for acylation reactions. Acyl fluorides are generally more reactive than other acyl halides, such as acyl chlorides or anhydrides.
An acyl chloride is a functional group with the formula RCOCl, where R is an alkyl or aryl group. It is commonly used in organic chemistry as a reactive intermediate for the synthesis of carboxylic acids, esters, and amides. Acyl chlorides are highly reactive compounds due to the presence of the electrophilic acyl group.

Aspirin is generally produced by the following mechanism (starting from basic materials) Phenol --(NaOH, CO2, heat)--> Sodium Salicylate (+para isomer) --(H2SO4)--> Salicylic acid --(acetic anhydride)--> acetylsalicylic acid (Aspirin) Due to the myriad of organic reactions, there are multiple possibilities at each stage. However, the above is the most efficient and common way of synthesizing Aspirin. For example, the last reaction (esterification) may be accomplished by using an acyl halide instead of an anhydride (e.g. ethanoyl/acetic chloride instead of acetic anhydride). However, the acyl halide is more costly to synthesize and more unstable to handle.
An acyl halide is an organic compound containing an acyl functional group directly attached to a halogen.

An anhydride is not an acid and not a base.
