I just want to know If Time is actually moving forward in one direction or is there anything in the universe for which the time is actually at rest despite the fact that it's actually moving forward for everything.

Particles that travel at light speed such as photons experience no time passage (their proper time is stationary). Other bodies that experience strong gravitational fields such as those close to black holes will appear to us to have their clocks stopped but they themselves will see time progressing normally. The whole question of the passage of time and direction of the arrow of time is a very deep and interesting one. For instance, positrons can be thought of as electrons moving backwards in time. For more info look up “arrow of time” and “Feynman diagrams”.
