Ya, it is the second stage in respiration.
While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration.
No, the Calvin cycle is not a part of cellular respiration. It is a series of reactions that take place in the chloroplasts of plants during photosynthesis to convert carbon dioxide into glucose. Cellular respiration occurs in the mitochondria and is the process by which cells generate energy from glucose.
It is the citric acid cycle that is part of cellular respiration and is named after Hans Adolf Krebs.

Kreb cycle
The main job of Kreb cycle is to generate energy. It is a part of cellular respiration.
2 ATP are made
Glycolysis is the first step in cellular respiration, where glucose is broken down to produce pyruvate and a small amount of ATP. Cellular respiration then continues with the Krebs cycle and oxidative phosphorylation to produce more ATP. Essentially, glycolysis initiates the process of breaking down glucose to generate energy through cellular respiration.
Citric acid is formed during the citric acid (Krebs) cycle, which is the second stage of cellular respiration. In this cycle, acetyl-CoA is oxidized to produce ATP, CO2, and NADH in a series of reactions that take place in the mitochondria.
This part of cellular respiration is called Glycolysis.
