Not the best, and not very accurate, but quite thorough in their assessment in an understandable way, of how a Pope is elected, and who can become Pope.

Yes, there are indeed several requirements to become a Pope as stated :

1. Male (only males can become priests, as we stay faithful to the Sacred Tradition that has begun since the Apostles, on the teachings passed down from Christ).

2. Baptised as Catholic (Baptised with water by a priest in the name of the Father, Son, and the Holy Spirit).

Although those two are the stated requirements, but indeed, usually Cardinals select among themselves for candidates to become the next Pope, since they have the experience and the required abilities and knowledge needed to lead the Universal Church. It is only rarely than bishops and archbishops are selected, and even many did not make it to be elected.

The Popes, Cardinals, Archbishops, and Bishops are all bishops, and hence, not each a separate religious order by themselves. The Pope is simply at the highest, being the Bishop of Rome, and thus successor of St. Peter the Apostle, leader of the Universal Church. The Cardinals as the Pope’s assistants either in Rome or around the world, and the archbishops and bishops as the local shepherds guiding the flock of Christ.

The priests as the soldiers that bring the work of Christ to all His beloved children. Let us pray for all of them!
