Parameshthi means one established in the highest place. The five are not five gods and not five offices. They are five conditions a soul can be in, listed in descending order of spiritual attainment.
The distinction matters. A person is not an Acharya because a committee elected them; they are an Acharya because they keep the great vows in full and carry a particular responsibility within the order. Remove the conduct and the designation goes with it.
Arihant and Siddha are both liberated in the sense that matters, but they differ in one respect: the Arihant still has a body and the Siddha does not.
An Arihant has destroyed the four ghati karmas, the ones that obscure the soul itself. What remains are the four aghati karmas, which only determine how long the body lasts and what it is like. When those exhaust themselves at the end of that life, the soul becomes a Siddha and rises to the siddhashila at the very top of the universe, where it remains, unchanging, for ever.
Acharya, Upadhyaya and Sadhu are living ascetics. All three keep the same five great vows; what separates them is the responsibility each carries within the order.
The Jain flag carries five horizontal bands, one for each Parameshthi. Each band also stands for one of the five great vows, so the flag states the ideal and the discipline that reaches it in the same object.
They are venerated, not petitioned. A Siddha has no connection with the world and grants nothing; an Arihant teaches but does not intervene. Veneration in Jain practice is a way of holding an ideal in view, not a transaction.
