No, because constant velocity means constant speed and constant direction
Yes. Velocity is rate (or speed) in a given direction. If you change your direction but not your rate (or speed) then you have changed your velocity without changing speed.
No. If the speed varies, the body accelerates, and velocity cannot be constant.
Yes, if you are going in a circle or otherwise changing direction.
Yes, if you are going in a circle or otherwise changing direction.

velocity means speed of an object and in a definite direction.That shows velocity changes with speed
The speed is the MAGNITUDE of the velocity, i.e., without regard to the direction.
In common speech, velocity means speed, they are the same thing.
A body moving at a uniform speed may have a uniform velocity, or its velocity could be changing. How could that be? Let's look. The difference between speed and velocity is that velocity is speed.
no
No. A body with constant velocity is either stationary or going at constant speed in a constant direction. The usual interpretation of speed and velocity goes like this. A velocity is a vector with magnitude and direction. The magnitude is usually called its speed. Changing a speed must change the length of the vector and changing the length of the velocity vector has to change the velocity.
