Recently, Tsallis, Rényi, and Sharma-Mittal entropies have widely been used to study the gravitational and cosmological setups.

We consider a flat FRW universe with linear interaction between dark energy and dark matter.

We discuss the dark energy models using Tsallis, Rényi, and Sharma-Mittal entropies in the framework of Chern-Simons modified gravity.

We explore various cosmological parameters (equation of state parameter, squared sound of speed ) and cosmological plane ( ω d - ω d ′ , where ω d ′ is the evolutionary equation of state parameter).

It is observed that the equation of state parameter gives quintessence-like nature of the universe in most of the cases.

Also, the squared speed of sound shows stability of Tsallis and Rényi dark energy model but unstable behavior for Sharma-Mittal dark energy model.

The ω d - ω d ′ plane represents the thawing region for all dark energy models.
