  NASA's all-sky survey mission, the Transiting Exoplanet Survey Satellite
(TESS), is specifically engineered to detect exoplanets that transit bright
stars. Thus far, TESS has successfully identified approximately 400 transiting
exoplanets, in addition to roughly 6000 candidate exoplanets pending
confirmation. In this study, we present the results of our ongoing project, the
Validation of Transiting Exoplanets using Statistical Tools (VaTEST). Our
dedicated effort is focused on the confirmation and characterization of new
exoplanets through the application of statistical validation tools. Through a
combination of ground-based telescope data, high-resolution imaging, and the
utilization of the statistical validation tool known as \texttt{TRICERATOPS},
we have successfully discovered eight potential super-Earths. These planets
bear the designations: TOI-238b (1.61$^{+0.09} _{-0.10}$ R$_\oplus$), TOI-771b
(1.42$^{+0.11} _{-0.09}$ R$_\oplus$), TOI-871b (1.66$^{+0.11} _{-0.11}$
R$_\oplus$), TOI-1467b (1.83$^{+0.16} _{-0.15}$ R$_\oplus$), TOI-1739b
(1.69$^{+0.10} _{-0.08}$ R$_\oplus$), TOI-2068b (1.82$^{+0.16} _{-0.15}$
R$_\oplus$), TOI-4559b (1.42$^{+0.13} _{-0.11}$ R$_\oplus$), and TOI-5799b
(1.62$^{+0.19} _{-0.13}$ R$_\oplus$). Among all these planets, six of them fall
within the region known as 'keystone planets,' which makes them particularly
interesting for study. Based on the location of TOI-771b and TOI-4559b below
the radius valley we characterized them as likely super-Earths, though radial
velocity mass measurements for these planets will provide more details about
their characterization. It is noteworthy that planets within the size range
investigated herein are absent from our own solar system, making their study
crucial for gaining insights into the evolutionary stages between Earth and
Neptune.
