Duplicate Daemons CAN proc their skills multiple times. I've tried it out with 5 Max Wind Weasels, in the past En Garde events.

While the choice of having multiple Sprites in your team would be dependent on what Daemons you currently possess and your current level, in general, I support the notion of having all three in Defense Team. Going off of what Omatsuu~ said, the proc percentage per Sprite is 70%, and if you have one of your Sprite as a leader, the chance of you having 45% Divina Reduction is 42% (going by http://ayakashi-ghost-guild.wikia.com/wiki/Skill_Percentage).

There are better Daemons out there, but until you acquire them, having multiple Sprites in your Defense Team is recommended.
