Ok, this is another odd question

So…I have decided to make a fire emblem like game, and while i still have some doubts over the damage and skills/spell system, i know have new questions…

1.) how do i make an enemy ai move and attack in a hexagonal grid?

2.) is it possible to make a fire emblem ui?

3.) is it possible to make combat animations liek fire emblem where it transitions to a sideview battle and the battle plays out?
