Yes! This is correct.
In lecture, Lavelle stated that a single bond (such as that between F-F) is one sigma bond. A double bond (such as that between 0=0) is one sigma bond and one pi bond. A triple bond is one sigma and two pi bonds.
Yes, if you can imagine. You have two atoms that both contain p-orbitals. When they form a bond, 1 of the 3 p-orbitals of each atom interact head-on with a lot of overlap. The other 2 orbitals are parallel to its partner orbital in the other atom. These orbitals will form pi bonds.
