Can a particle in one dimensional with zero speed may have non zero velocity?
There are fundamental errors in the question. A particle is three dimentional and cannot exist in a one dimentional universe, nor can velocity.
Is it possible in straight line motion particle have 0 speed and a non-zero velocity .explain?
Sounds like a trick question. The answer is no. Speed is a scalar with magnitude only and velocity is a vector with magnitude (speed) and direction. So If traveling with velocity in a straight line it has speed..
A net external force acts on a particle This net force is not equal to zero is this sufficient information to conclude that the velocity of the particle changes?
Yes. F=ma if f is non zero then a is non zero and the velocity changes if the particle is not constrained, free to move.
Is it possible that there is a non-zero acceleration but with a speed of value zero?
Not with any sensible definition of "acceleration" and "velocity." You CAN accelerate an object and have it end up at zero velocity. But, if the acceleration remains a non-zero number, then the velocity can NOT remain at zero. Your question is like asking, "Can the value of a quantity change, but also remain the same?"
Can a particle with maximum speed have zero acceleration?
Yes. Velocity implies both a magnitude and a direction. An object going around in a circle moves at a constant speed, but the direction, and therefore the velocity, is changing.Yes.

Can a body have nonzero average speed but have zero average velocity give example?
An object moving in a circular path at constant speed will have a non-zero average speed and zero average velocity since velocity is a vector parameter,
Can it have zero acceleration and non zero velocity?
Yes this is possible, when the velocity is constant. When velocity is constant there is no change in velocity, if there is no change in velocity then is no acceraltion. e.g. : a car traveling at a constant speed of 40m/s

Is it possible that there is a non-zero acceleration but with a speed of value zero?
Not with any sensible definition of "acceleration" and "velocity." You CAN accelerate an object and have it end up at zero velocity. But, if the acceleration remains a non-zero number, then the velocity can NOT remain at zero. Your question is like asking, "Can the value of a quantity change, but also remain the same?"
Is it possible that a particle has zero velocity but still have a acceleration?
If the velocity equals zero, the acceleration is also zero because the velocity hasn't changed, thus, the particle isn't accelerating anywhere. This is not exactly true; at an instant in time the acceleration can be non-zero while the velocity is zero. However, this would change the velocity to non-zero after any amount of time. An example of this is when you throw a ball into the air: at it's highest point, the velocity is zero (it changes from going upward to going downward, passing through zero for an instant). However the acceleration is downward the entire time.
How would you differentiate between speed and velocity?
Speed is the magnitude of distance travelled per unit time, whereas velocity depends on the magnitude of distance travelled as well as the direction of motion. Speed is a scalar quantity, velocity is a vector. Speed cannot be negative, velocity can be negative. Average speed of an object after travelling a certain distance is always non-zero, but for velocity the average velocity can be zero (this follows from the previous idea).
What is the difference between constant velocity and variable velocity?
Constant velocity has speed always constant along the direction with respect to time. Variable velocity changes its speed with respect to time. Constant velocity has zero acceleration. Variable velocity has non-zero acceleration . An object moving at a constant velocity maintains both the same speed and direction. An object moving at a variable velocity can be changing speed or direction of travel or both.
Does an object experiencing a constant velocity have a zero or non-zero value for acceleration?
If an object is sustaining a constant velocity it has 0 acceleration, because acceleration is either increasing or decreasing speed.
