If a Confluence is copied, the effect that creates the copy will usually allow you to choose new targets, but you can't choose new modes.
Fiery Confluence
If the first or second modes are chosen multiple times, each of those modes represents a separate damage-dealing event. For example, if your opponent casts Fiery Confluence choosing the second mode three times, and you control Guardian Seraph (a creature with the ability "If a source an opponent controls would deal damage to you, prevent 1 of that damage"), you'll be dealt a total of 3 damage.
If a mode requires a target, you can select that mode only if there's a legal target available. Ignore the targeting requirements for modes you don't choose. Each time you select that mode, you can choose a different target, or you can choose the same target.
