No. If the speed varies, the body accelerates, and velocity cannot be constant.
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.
Yes, if you are going in a circle or otherwise changing direction.
Yes, if you are going in a circle or otherwise changing direction.
Yes, if you are going in a circle or otherwise changing direction.
No, not at all possible. But constant speed with changing velocity is possible.
no
Of course. In fact, in order to have constant velocity, it must have constant speed.What you really want to know: Can a body have changing velocity when it has constant speed ?The answer to that one is also "yes", for example when it is moving in a circle, the speed is constant but the velocity is changing all the time (in direction).
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.
No, constant speed implies that the body is moving at a consistent rate, while variable velocity means the direction of motion is changing. It is not possible for a body to have both constant speed and variable velocity simultaneously.

Speed is a scalar quantity while velocity is a vector quantity.It is possible that an object can have constant speed but if speed is constant while direction of motion is changing constantly then it means that body has variable velocity.An example of this phenomena is a body moving in a circle whose speed is constant but velocity is changing every instant due to change in direction at every instant.
