Here we go.

a) $\frac{17\pi}{5}$ is in the third quadrant, and the angle is $\frac{7\pi}{5}-\pi=\boxed{\frac{2\pi}{5}}$.

b) $614$ is in the third quadrant, and the angle is $614-360-180=\boxed{74}$

c) $\frac{21\pi}{4}$ is in the first quadrant, so the angle is $\boxed{\frac{\pi}{4}}$

d) $240$ is in the third quadrant, so the angle is $240-180=\boxed{60}$.
