What you need to do is create a class/struct representing a leaf. This will contain information specific to each leaf.

In pseudocode (plus real STL code):
class Leaf{
position;
velocity;
colour;
Leaf(){
position = randomVector();
velocity = randomVector();
colour = randomColour();
}
};

void makeLeaves(int numberOfLeaves, std::vector<Leaf> leaves){
for each leaf {
Leaf l;
leaves.push_back(l);
}
}

void updateLeaves(std::vector<Leaf> leaves){
std::vector<Leaf>::iterator currentLeaf = leaves.begin();
while (currentLeaf != leaves.end()){
currentLeaf->updatePositionAndVelocity();
currentLeaf++;
}
}

void drawLeaves(std::vector<Leaf> leaves){
std::vector<Leaf>::iterator currentLeaf = leaves.begin();
while (currentLeaf != leaves.end()){
currentLeaf->draw();
currentLeaf++;
}
}
