Is it possible to add two vectors of unequal magnitudes and get zero? Is it possible to add three vectors of equal magnitudes and get zero?

No, by adding two unequal vectors in magnitude we cannot get a zero vector. In order to get a zero vector, they must be equal in magnitude and opposite in direction such that they cancel out other.

Yes, we can get a zero vector by adding three different vectors of equal magnitude. Assume that 3 vectors of equal magnitude are originating from a point such that the angle between them is 120° each, now if we take the resultant of any two vectors, it would cancel out the third vector.
