The only way that two vectors add up to zero is if they have equal magnitude and opposite direction. If the magnitudes are not equal then no, they cannot give a zero resultant.
A couple: 2 parallel forces equal in magnitude, but opposite in direction separated by a distance.
No.
Zero.
Three One is obviously out. Two is out because if two unequal forces n and p act on an object the resultant with the minimum force in magnitude is |n - p|, which will never be 0 if n =/= p. Three can be easily resolved with a quick example. Imagine an object with three concurrent forces acting on it. Two forces, n = 3 N and p = 4 N, create an angle with each other such that the resultant is 5 N. 180 degrees from the resultant, a force, r = 5 N, is acting on the object. Thus three unequal vectors on an object can result in 0.

Three. Equal forces, two.
When there are balanced forces acting on an object, the resultant force is zero. This means that the forces are equal in magnitude and opposite in direction, resulting in no acceleration of the object.

No.
Do you mean buoyancy? They are said to be balanced, because their net sum, or resultant, is zero.

Zero.
No, two vectors of unequal magnitude cannot have a sum of zero. The resultant of adding two vectors is determined both by their magnitudes and directions. If the vectors have unequal magnitudes, the resultant vector will have a magnitude that is at least as large as the larger of the two original vectors.
