It is a magnitude that has a size and a direction. You can also express it as having components in different directions; for example, in the x-direction and in the y-direction.
Vector quantities are the quantities that have magnitude as well as direction. To express a vector quantity, we must specify the direction along with the magnitude. Examples are :- velocity, acceleration, torque, momentum, impulse, amplitude, wavelength,etc..
Its either reality based (vertical is up-down, horizontal is ground distance) or it's purely arbitrary.
Yes. Force has both magnitude and direction. Force is an example of a vector quantity. A vector has two components: magnitude and direction. Let me give a simple example to illustrate. Suppose a door is partially open. CASE 1: You push on the outer door knob with a force of 10 pounds. Result: the door will become more closed. Maybe it will slam shut. CASE 2: You push on the inner door knob with the same force of 10 pounds, but in the opposite direction to your earlier push. Result, the door moves to be more open. Maybe it will swing completely open. (If you and a friend pushed on the door knobs at the same time with 10 pounds force each, the forces would cancel and the door would not move.) -Dr. Q

The Richter scale expresses the relative magnitude of an earthquake, which is a measure of the energy released at the focus of an earthquake.
It is a magnitude that has a size and a direction. You can also express it as having components in different directions; for example, in the x-direction and in the y-direction.
I/you/we/they express. He/she/it expresses. The present participle is expressing.

Yes, friction is a force it possesses magnitude and direction. It's magnitude and direction are measured in in Newtons and radians (or other angular measurement) which are written in numbers.No friction is a phenomenon; numbers a human idea. But numbers can be used by humans to express and calculate many things which concern friction.
it is often said that music expresses the real you.
Number!
