The discovery of extrasolar planets outside our solar system and around other stars is now well underway. In the presented paper, calculations of some physical properties for confirmed exoplanets have been done. We estimated physical properties of exoplanets such as the Semi-major axis for 35 potentially habitable exoplanets, the mass of planets by applying Kepler's third Law around the mass of solar, Jupiter, and Earth-mass, stellar luminosity, and radial velocity amplitude. The MR relationship was investigated for 74 potentially habitable exoplanets of three different groups of extrasolar planets, Subterran (Mars-size), Terran (Earth-size), and Superterran (Super-Earths or Mini-Neptunes) introduced in PHL, and found well coefficient values for each group. The minimum and maximum values for the radius and mass of exoplanets have been selected from 0.4 < R < 2.5 R and 0.1 < M < 10 M and estimated Chen and kipping (Chen & Kipping, 2016) equation to compare with the previous mass valued of planets. The same MR relationship estimated also for a large number of confirmed exoplanets (3907) with mass and radius of 0.1 < M < 1600 M and 0.4 < R < 100 R respectively and the result classified with 12 groups in radius and mass with good coefficient values for each group. This is a new possible classification that may need more effort for concluding a better understanding of the properties and varieties of the exoplanets.
