The terms internal energy, enthalpy, entropy are state functions. Are change in internal energy($\Delta$U or $\Delta$E),change in enthalpy($\Delta$H) and change in entropy($\Delta$S) state functions?

No, because they depend not only on the current state but also on a previous state. However, it is true that these functions do not depend on the path taken between the two states.
