The first Liturgy used in the Coptic Church (which I see you mention an interest in in your jurisdiction) was the Liturgy of St. Mark. Of course St. Mark wrote the Liturgy, but He and the other Apostles received at least the form of the Liturgy from Christ between the Resurrection and Ascension.
St. Cyril the Great (4th-5th century) revised St. Mark's Liturgy by translating it from Greek to Coptic, adding additional intercessions, and moving the intercessions earlier in the Liturgy (this was to allow catechumens to stay longer before being dismissed). This Liturgy is still commonly prayed today, usually during Lent.
The Liturgy of St. Basil (4th century) is the Liturgy used most frequently today in the Coptic Church. It follows the same basic form as the Liturgy of St. Mark, there is no radically reorganization here. However, when St. Mark wrote the Liturgy, the New Testament as we know it did not exist. St. Basil's Liturgy was described as "a patch-work of Scripture".
Both these Liturgies are addressed to God the Father.
The Liturgy of St. Gregory (5th century) expands some sections using the theological language that had developed by then, and is addressed to Christ. The form is still very similar though. This Liturgy is commonly used on feasts.
Many prayers are different between the three Liturgies, but at the same time they contain all of the same essential prayers.
There have been further additions to the Liturgy over the years, including more intercessions, rearrangements (at some point the offertory was moved from before the Anaphora to before the Liturgy of the Word), and additions. The core remains fairly unchanging, but it is a living tradition.
