(-y, x) is generally a point in the Cartesian plane - not a vector nor a scalar. You can have a vector going from any point in the plane to the point (-y, x) but that is not the same thing.
Yes. This is the basis of cartesian vector notation. With cartesian coordinates, vectors in 2D are represented by two vectors, those in 3D are represented by three. Vectors are generally represented by three vectors, but even if the vector was not in an axial plane, it would be possible to represent the vector as the sum of two vectors at right angles to eachother.
It is a translation on the Cartesian plane

Generally vectors are displayed in parenthesis with the vector components separated by a comma. If there are vectors within another vector then brackets are used for the internal vector.
The components are independent so it isn't possible to derive one component from another (in general).

A vector is a magnitude with a direction, so if you have a line that is +2 on the x-axis and +2 on the y-axis, that would be a vector.
A vector magnitude is the number that is associated to the length of the vector.

A vector represented in Cartesian plane. For eg velocity of particle moving on road taking into account length and breadth of road. An ant moving on a floo
No, there is no direction associated with it.
Unit vectors are perpendicular. Their dot product is zero. That means that no unit vector has any component that is parallel to another unit vector.
