The answer to your first question is, yes, the answer to your second I will copy and paste for you:
The people of the church do not create saints, they recognize as saints those whom God himself has glorified, seeing in their lives true love for God and their neighbors.
From the beginning, the Church recognized the righteous ancestors of Christ, forefathers, as grace-filled men and women whose lives were pleasing to God. Also the prophets who predicted Christ's coming and the apostles and evangelists who proclaimed the Gospel were assumed to be saints.
Next the martyrs and confessors who risked their lives and shed their blood in witness to Christ were also recognized as saints.
In time, ascetics who followed Christ through self denial, were numbered among the saints.
and who fought against and proclaimed the true faith are recognized by the Church as saints.
Today, holy people, in all walks of life, can be recognized as saints.
So, some saints are "glorified" that is added to the calendar for commemoration and this is determined at the local level then the universal level at Synods and the like. Other Saints, we may never know, but God knows. This may not be very helpful, especially given the fact I am not very Orthodox and unworthy of the name as is constantly pointed out to me..but this is my understanding of the process, so take it with a grain of salt.
