Yes.
The vertical component of the projectile's motion is uniformly accelerated, no matter what the angle of launch was.
No, it is uniformly decelerated for the first half and uniformly accelerated motion in the next half in two dimensions.
Yes, the projectile needs to be accelerated to overcome the acceleration of gravity.
In uniform motion, object travel at fixed and constant speed and uniformly accelerated motion the speed of the object increases uniformly.
Projectile motion has two components horizontal motion and vertical motion. Gravity affects only the vertical motion of projectile motion.

yes, acceleration is constant in uniform circular motion
Acceleration = change of speed / time
It means that acceleration is constant. This meaning that velocity is varying with respect to time, we see this by this formula (v - v(initial) ) / t (Time).
The motion of a projectile is a combination of two motions, a constant speed motion in the horizontal direction, and an accelerated motion in the vertical direction. The velocity component that changes along the path is Vy.
