  Pulsating stars are remarkable objects for stellar astrophysics. Their
pulsation frequencies allow us to probe the internal structure of stars. One of
the most known groups of pulsating stars is $\delta$ Scuti variables which
could be used to understand the energy transfer mechanism in A-F type stars.
Therefore, in the current study, we focused on the discovery of $\delta$ Scuti
stars. For this investigation, we followed some criteria. First, we inspected
TESS database by eye and discovered some single stars that exhibit
pulsation-like behaviour. Our second criterion is $T_{\rm eff}$ and $\log g$
range. The $\delta$ Scuti stars generally have $T_{\rm eff}$ and $\log g$ value
in a range of 6300\,$-$\,8500\,K and 3.2\,$-$\,4.3, respectively. Hence, we
selected the stars which have TIC $T_{\rm eff}$ and $\log g$ values in these
ranges. The other criterion is the pulsating frequency. A frequency analysis
was performed for all the candidate stars. In addition, $M_{V}$, $L$ and also
$M_{bol}$ parameters of the target stars were determined to calculate the
pulsation constants and show their positions in the H-R diagram. The final
pulsation type classification was made by considering the frequency ranges and
pulsation constants of the stars. As a result of the study, five $\delta$
Scuti, one $\gamma$ Doradus and four hybrid systems were discovered.
