"  Ultra Rapid Rampage after a single stack?"

Hecarim's Rampage (theoretically) has 0 CD after a single stack but is limited in cooldown by the animation of the ability itself. There's also a cooldown indicator on the ability cast button but I can't remember what it displayed, possibly the time it takes for the animation to complete.

"How do several  Demacian Standards in a line and  Dragon Strike interact?"

Jarvan will jump to the furthest Demacian Standard his Dragon Strike encounters.

"Multiple axes from  Undertow to pick up?"

The axe disappears when Undertow is off cooldown.
