Decelerating means that the speed, i.e., the absolute value of the velocity, decreases over time.
If the velocity is decreasing, the object is decelerating.
It means the object is decelerating - slowing down rather than speeding up. You can think of it as negative acceleration.
An object with no force on it will either be at rest or moving with a steady velocity, an object with an unbalanced force, which is the same as saying it has a net force on it, will be accelerating (or decelerating)
Decelerating means to slow down. It means that an object is moving at an increasingly slower speed.
Then the object accelerates; its velocity changes.Then the object accelerates; its velocity changes.Then the object accelerates; its velocity changes.Then the object accelerates; its velocity changes.

Yes, if it is already moving East but decelerating i.e. accelerating to the west. The other condition when there is velocity to the east while accelerating to the west is when it is moving at an angle to the East-West line.
decelerating
If the speed/time graph slops negatively, that's an indication that the speed is decreasing, i.e. the object is slowing down. The negative slop is also called negative acceleration, since acceleration is the rate of change of velocity.

Speed and Velocity are two words that mean the same. You may mean, "Can Velocity be 0 but acceleration not 0". Yes, this occurs when a moving object is changing direction (say from moving forwards to moving backwards) or is just about to move or, at that very instant has just come to a halt. In all these cases, speed /velocity is zero but the body is accelerating. Don't forget, the word acceleration is also used when an object is decelerating (slowing down).
if under uniform acceleration or deceleration v = u + (a*t) where: v = instantaneous velocity u = initial velocity a = acceleration (negative if decelerating) t = time elapsed
the velocity of an object is its speed and direction
