What do you mean by redox reaction ?

$⟶$ Redox reaction include all chemical reaction in whichatoms thier oxidation state change ;

in general , redox reaction involve the transfer of electrons between species.

Redox $⟶$ Red +ox $⟶$ Reduction+oxidation

It is a reduction -- oxidation reaction.

$⟶$ All of the examples given in question include reduction or oxidation or both.
