What if an object is changing from -m4/s to -1m/s. Is the velocity becoming more positive or less positive? Is there acceleration in this?

What if an object is turning around so that it undergoes a change in velocity from 2m/s to -2m/s? Is the velocity becoming more positive or less positive? Is there acceleration while the object is turning?

I assume you mean -4 m/s to - 1 m/s. Well, you figure it out. Draw a number line from -10 to +10 and mark off where -4 and -1 is. When you move from one to the other, which direction do you move, positive or negative.
Is there acceleration in this?
If the velocity changes, there's acceleration.

Figure this one out the same way.
