i am given a voltage time graph for a capacitor circuit. How to find energy stored in that capacitor at various time instants? Can we just calculate by using $\frac{1}{2}CV^2$ We are given capacitance of that capacitor.

Yes. If $v_C(t)$ is the instantaneous voltage across the capacitor, the instantaneous stored energy is just
$$U_C(t) = \frac{C}{2}v^2_C(t)$$
