How to implement a sequence of moves

I am building a 2D RPG game. During the turn-based battle, I would like to move the character to an enemy's position, wait a few seconds to play the attack animation and then move the character back to her original position. I am thinking of playing these three actions in three coroutine but have no idea how to concatenate them.

Another question is if I have more than one character and would like to let them move at the same time, how can I do it? I really appreciate any code samples.
