A vector magnitude is the number that is associated to the length of the vector.
The "size" of a vector quantity - such as a force - is often called a MAGNITUDE.
a vector quantity has both direction (sign) and magnitude like displacement towards right or left (direction) and has a certain value (magnitude)
Any physical quantity which has both direction and magnitude is called a vector. A quantity must also obey the 'Triangle law of vector addition' to be called as a vector. For example displacement is a vector, u can say a person moved 5 km (magnitude) along west(direction). But electric current is not a vector, it has magnitude and its direction is from +ve terminal to -ve terminal but it doesn't obey triangle law. Rather currents are added as scalars.
The direction of the arrow represents the direction of the force; the length of the arrow is proportional to the magnitude of the force.
Speed is the rate of which an object is moving altogether and is a scalar quantity and thus only requires a magnitude and is found by the use of the formula speed=distance/time SI unit = m.s-1 Velocity is the rate of which a object is moving in a given direction, so is vector quantity and both a magnitude and direction are required found by the formula velocity=displacement/time SI unit = m.s-2

Nothing. A magnitude is part of a vector. For example, for the vector "10 metres due East", 10 metres is the magnitude of the vector and East is the direction of the vector.
A vector is described by magnitude and direction (a scalar has only magnitude).
That depends on what the vector, itself, represents. For example, if the vector represents velocity, then the magnitude of the vector represents speed. If the vector represents displacement, then the magnitude of the vector represents distance.
no a vector cannot have a component greater than the magnitude of vector
The magnitude of a vector is a scalar.
can a magnitude of a vector has negative value?
Yes.
A null vector has no magnitude, a negative vector does have a magnitude but it is in the direction opposite to that of the reference vector.
can a vector have a component greater than the vector magnitude
No. The size of the size of the vector drawn indicates the magnitude.
