Psst. You should be able to right-click the icons to display a tooltip that shows what those actions are.

It's Cheer(I forget the actual name) Beg, Bribe, Flee, and I think autobattle again.
"Cheer" gives a party member a temporary offensive boost,
Beg will do a check against an enemy's Mercy value and provides a chance for them to flee,
Bribe will do a check against an enemy's Greed value and does the same thing as beg except it costs money,
Flee will have you escape from battle, but usually at the cost of an item or some money.
You can check an enemy's Mercy, Greed, Brains, Toughness, and HP stats by double-clicking their icon during battle.
