Is potential energy on the surface of earth is always zero?
That depends on what reference level you have chosen. If the (arbitrary) reference level you chose is Earth's surface, then anything on the Earth's surface has zero potential energy. If you choose some higher reference level, an object on Earth's surface has a negative potential energy. If you choose a lower reference level, an object on Earth's surface would have a positive potential energy.
Does the displacement arrow depend on the choice of reference point?
Yes and no.Some use "displacement" only to describe a change in the position of an object from some initial starting point to some ending point. That is, there is a distinction between "position" and "displacement." The position would be defined relative to a reference point. In that case the arrow depends only on where the particle was and where it ended up and the reference point does not matter.Others use a definition for displacement which describes the difference between an object's position and a fixed reference point. That is, how far an object is displaced from a certain point even if the object had never been at that point. A distinction between position and displacement is not made. For this latter definition, the choice of reference point will make a difference in the direction of the arrow.In physics problems one usually only cares about the changes in position (and velocity, etc) and the choice of reference point will not affect these.
Does position affect velocity?
Sometimes. If an object is falling, it's position relative to the Earth, will affect its velocity. Between two parallel electric plates, the velocity of an charged oil drop is independent of its position (more or less).
Why does a description of position depend on a reference point?
Description of position depends on a reference point because there is no other way to do it. A reference point is observable, so based on that observation, you can then describe where something else is. All locations are described that way, although there are many different kinds of reference points that are used. For example, a street address, 233 Main St., uses a street as a reference point. Mathematically, a Cartesian coordinate system is the most commonly used way to establish reference points. The use of lines of latitude and longitude allow is to locate anything on the surface of the Earth. If we wishes to locate another planet than the Earth, in our solar system, we would start by describing the distance of that planet from the sun.

HOW TO write integers that can be used to represent the situation like a debit of 60?
If you use positive numbers to represent money which you have or are owed (credit), then use negative numbers to represent debits.Remember, though, that sometimes the choice of which of the two is positive is arbitrary and depends on you. If I owe you money, the situation would be represented by a negative number in my accounts but a positive entry in yours.
What is the directional term meaning below a point of reference?
The directional term meaning below a point of reference is "inferior." It is often used in anatomy to describe the position of one body part in relation to another, indicating that it is situated lower or underneath.
