What Team should I make?

All my 5 stars are lvl 40 so it is time to make the ultimate team (that I can right now).
So here is a list of all of my lvl 40 5 stars with their ivs:
Summer Robin (F) +Def -Hp
Celica Neutral
Titania +Def -Res
Setsuna +Def -Spd
Sonya +Spd -Res
Leon +Hp -Res
Genny +Spd -Res
Ninian +Spd -Def
Brave Ike +Spd -Atk
Linde +Atk -Spd
Brave Roy Neutral
Brave Lyn +Atk -Def
and Leo +Res -Hp

If you can also help me with what skills they can learn too that would be a great help to.
