It is a measure which has a direction as well as a value.
a vector with nothing in it
A resultant vector is one vector which can replace all the other vectors and produce the same effect.

It stands for gradient vector flow.
A negative vector is a vector that has the opposite direction of the original vector but the same magnitude. It is obtained by multiplying the original vector by -1. In other words, if the original vector points in a certain direction, the negative vector points in the exact opposite direction.
A force is a vector - in two dimensions, you can represent it on paper as an arrow. Such vector/arrows have a size, and a direction. The size is usually called the "magnitude".
A primitive translational vector is the smallest vector that can translate a point in a crystal lattice to a similar point. It defines the repeating unit cells in a crystal lattice and is used to describe the periodicity of the lattice structure.
I think you meant to ask for finding a perpendicular vector, rather than parallel. If that is the case, the cross product of two non-parallel vectors will produce a vector which is perpendicular to both of them, unless they are parallel, which the cross product = 0. (a zero vector)
A unit vector has a length (magnitude) equal to 1 (one unit). A rectangular vector is a coordinate vector specified by components that define a rectangle (or rectangular prism in three dimensions, and similar shapes in greater dimensions). The starting point and terminal point of the vector lie at opposite ends of the rectangle (or prism, etc.).

Yes, a vector can be represented in terms of a unit vector which is in the same direction as the vector. it will be the unit vector in the direction of the vector times the magnitude of the vector.
Resolving a vector into components means breaking down the vector into perpendicular vectors that align along the coordinate axes. For example, a vector of magnitude 10 at an angle of 30 degrees with the x-axis can be resolved into x-component = 10cos(30) and y-component = 10sin(30) where cos(30) = √3/2 and sin(30) = 1/2.
