Well, I'll assume you mean in a message box and not just in general. You can show a name by using \n[a], where a is the ID of an actor. So \n[1] would show the name of Actor 1 (Aluxes); \n[2] would show the name of actor 2, etc... \n[0] would show the name of the party leader.
To show faces (I assume you are using XP since this would be too obvious in VX), you can either do it by importing faces into the Picture folder of graphics and showing them with Show Picture, or you can do it by various scripts (like
dubealex's AMS or
ccoa's UMS). They each come with a full set of instructions for using faces.
