It is a vector that has the opposite direction to the reference positive direction. (A vector is one point in space relative to another.) Negative vector is the opposite direction
Basically, a scalar magnitude is one in which the direction is not relevant; a vector magnitude is one in which the direction is relevant. A scalar can be represented by a single real number; a vector requires at least two numbers (for example, the x-component and the y-component; or alternately a magnitude and a direction).
Normal to the surface is a vector which is perpendicular to that surface
Velocity is a vector. As every vector in includes direction and magnitude (as 'oppose' to scalar). If that is what you meant by this vague question.
The product of scalar and vector quantity is scalar.
a vector with nothing in it
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.).
A vector has 2 components - it's magnitude and direction. Concurrent vectors are 2 vectors that have the same direction but may have different magnitudes.
A resultant vector is one vector which can replace all the other vectors and produce the same effect.
A component of a vector can be thought of as an "effectiveness" of that vector in a given direction. It's actually a "piece" or "part" of the vector. A vector is a geometric object with the two characteristics of direction and magnitude. It is when we plot these in a coordinate system that we see the components appear. If we draw a graph with the standard x and y coordinates handed down to us from Descartes, we can more easily see the components. On the graph, draw a vector from the origin (0,0) to the point (5,5). We set the origin as the point of initiation of the vector, and the "little arrow" on the "head" or terminus of the vector is at (5,5). But that vector represents the sum of two other vectors. One is the vector from the origin that runs along the x-axis to (5,0) and the other is the vector that runs from the origin along the y-axis to (0,5). As stated, the sum of these other two vectors makes the original vector we drew. And each of these vectors, the x and y vectors we drew, is a component of the vector we are inspecting. The components of vectors can be expanded into a multitude of dimensions, and will be dependent on the system we use to plot them. Wikipedia has some additional information, and a link is provided.

It is a measure which has a direction as well as a value.

like they were meant to be written into a full story or they have a resolving ending
It stands for gradient vector flow.
