Projectile speed is the speed at which the projectile moves. But cooldowns is probably the cooldown between each attack. Yet attack speed also means the towers attack at a quicker rate. So probably cooldown reduction and attack speed increase is equal to each other, but projectile speed is a different thing.

Projectile lifespan is how long the projectile will last for. Ninja Monkey projectile lifespan is useful especially with Seeking Shuriken.

"All cooldowns reduced by X%" means all towers and their abilities have their cooldowns reduced by X percent. As I said in my first paragraph at the top: "probably the cooldown between each attack".
