Yes, speed can increase even if the acceleration decreases.
Acceleration is the rate of change of velocity.
Assume that for first 5 seconds, a body accelerates from rest at 10 m/s2. After 5 seconds, its velocity will be 5 x 10 = 50 m/s.
Assume that after 5 seconds, the acceleration changes to 5 m/s2. Even then the velocity will increase, but at a slower rate than it increased for the first 5 seconds.

Answer:
The acceleration is positive when it is in the direction of velocity and negative when it is opposite to the direction of velocity. If an object travels in a straight line and its velocity increases or decreases by equal amounts in equal intervals of time then the acceleration of the object is said to be uniform.
