Oh, dude, like, an example of non-acceleration would be when you're driving at a constant speed on a straight road and not changing your velocity. So, like, if you're cruising at a steady 60 mph and not hitting the gas or brakes, that's a non-example of acceleration. It's like being in a state of motionless motion, man.
Non-uniform acceleration occurs when an object's velocity changes unequally over time, resulting in a non-constant rate of acceleration. For example, a car that speeds up and slows down at different rates during a road trip experiences non-uniform acceleration.
If the graph of speed versus time is a straight line, then the acceleration is constant/uniform. If the graph is curved or has a sharp corner, the acceleration is non-uniform, i.e. not constant. A uniform acceleration means the speed changes by fixed amount every unit of time, e.g. +3 m/s every second.
For example, an object thrown upwards, when it is at its highest point. This situation is only possible for an instant - if the acceleration is non-zero, the velocity changes, and can therefore not remain at zero.
Yes, an object moving at a constant velocity has zero acceleration even though it has a non-zero velocity. For example, a car driving at a steady speed on a straight highway has a constant velocity but zero acceleration.
An object moving in a circular path at a constant speed experiences non-uniform acceleration because its direction is constantly changing. This is because acceleration is a vector quantity that includes changes in both magnitude and direction.

Freely falling body is a good example
"Uniform acceleration" means that acceleration doesn't change over time - usually for a fairly short time that you are considering. This is the case, for example, when an object drops under Earth's gravity - and air resistance is insignificant. "Non-uniform acceleration", of course, means that acceleration does change over time.

No. ME isn't capable of understanding this. Feisty with Beryl, OTOH....

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?"
Acceleration due to gravity is a uniform acceleration of 9.8m/s2.
For uniform motion, the acceleration is zero. For non-uniform motion, the acceleration is something different than zero - at least, most of the time.
Uniform (or constant) acceleration means that the acceleration doesn't change over time.
