each classify reaction should be either one of this.
acid�base neutralization
precipitation
redox
none of the above

Concepts and reason
The concept used to solve this problem is based on chemical reaction.
In a chemical reaction, two or more substances combine to form a new substance by forming or breaking a bond.

Fundamentals
Acid and base react to form salt and water this is known as acid-base neutralization reaction. Redox reaction is a chemical reaction which involves the transfer of electrons between two species. It is also called oxidation-reduction reaction.
Precipitation reaction is a reaction in which anions and cations combine to form an insoluble ionic solid in aqueous solution.

In this reaction, chlorine is reduced and oxygen is oxidized. Both reduction and oxidation occur in this reaction. Therefore, this is a redox reaction.

Part 1
[Answer]
‎The reaction is redox reaction.

In this reaction, because chlorine loses the electrons so it is a reducing agent and oxygen gains electrons so it is an oxidizing agent. Therefore, it is a redox reaction.

Part 2
[Answer]
‎The reaction is none of the above.

A double displacement reaction is a reaction in which two compounds react and cations and anions exchange their places to form new compounds.

Part - 3
The reaction mention in the question is as follow.

Part 3
[Answer]
‎The reaction is none of the above.

Part - 4
The reaction mention in the question is as follow.

Part 4
[Answer]
‎The reaction is precipitation reaction.

In this reaction, both reactants react to form insoluble ionic solid. Therefore, it is a precipitation reaction.

Part - 5
The reaction mention in the question is as follow.

In this reaction, nitrous acid acts as an acid and barium hydroxide acts as a base. So, barium hydroxide and nitrous acid react to form salt and water. Therefore, this reaction is acid-base reaction.

Part 5
[Answer]
‎The reaction is acid-base neutralization reaction.

Acid and base react to form salt and water this is known as acid-base neutralization reaction.
