How to destroy all actors of the same static mesh and how to get on which static mesh the player is currently standing?

Hi, Im trying to make a color switch game where the game would randomly chose a color and the players have 5 seconds to run to that color before every color except that color gets removed.
My question is: How to destroy all actors of the same static mesh and how to get on which static mesh the player is currently standing?
Here is my map for better understanding:
