While this sounds like a question that is specific to a certain situation, it sounds like you're talking about air resistance. It always opposes motion and (for small objects) is modeled as being proportional to the magnitude of velocity.
Having a net force always leads to an acceleration due to Newton's famous law; F = m * a. An acceleration is a change of velocity therefore a net force will always change the velocity of an object.
inertia
The velocity of object always changes with wanted or unwanted outer forces.
Wanted and unwanted outer forces will always change the velocity of an object.
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.
This is not always the case. But if an object moves in a circle, at constant speed, its velocity will change. Velocity is a vector - consisting of the magnitude (the speed), and a direction. So by definition, if the direction changes, the velocity changes - you have a different vector.
When velocity changes, that means that the object either moves faster, or moves slower, or moves in a different direction. Any of these changes is called "acceleration".

Force changes the velocity of an object by acceleration, a=F/m.

A single force on an object, or a net force ... the sum of all forces on it when the sumis not zero ... always changes the object's velocity ... speed, or direction, or both.
Yes, acceleration is the how the velocity changes. This also includes when an object turns
When velocity changes, that means that the object either moves faster, or moves slower, or moves in a different direction. Any of these changes is called "acceleration".
The change in velocity is just the change in velocity. The RATE of change of velocity - how quickly velocity changes - is usually called "acceleration".
