Just for the record, I went to the Russian interface of Wikipedia, typed in "Svyatoi Georgii" ("St George") and it spins-up this enormous list of St Georges and Holy Martyrs:
http://ru.wikipedia.org/wiki/Святой_ГеоргийThey are arranged broadly by category - the top eight have the title of "Saint", the others are all Holy Prophets, Holy Martyrs, Disciples, and other ranks of Holiness (according to the canons of the Russian Orthodox Church currently).
I haven't got time to decode them all, but here are the top 8 who have Saintly status (and are all discrete and separate individual St Georges, each with a separate life-story and saint's-day):
Георгий Победоносец — христианский святой, великомученикGeorge the Holder Of Victory - Christian saint, Great Holy Martyr
<---- this is the Anatolian oneСвятой великий князь Георгий (Юрий) Всеволодович Владимирский (сын Всеволода Большое Гнездо)Saintly Grand-Prince George Of The Great Nest Of St Vladimir (son of Vsevolod Great-Nest)

Святой Георгий, епископ АмастридскийSaint George, Archbishop of Amastrida
Amid the further 32 George-named martyrs, etc there are several more titled as full Saints (ie with a record of miracles attested to their names):
Святой Георгий ШенкурскийSt George Shenkursky
вятой Георгий, день памяти — 26 (13 ст. ст.) апреляSt George, with a Name-Day on 26th April (which differs from the other St Georges so far mentioned)
Святой Георгий, день памяти — 10 февраля (28 января ст. ст.) St George, celebrated on 10th February (another new and different George)
Святой Георгий, день памяти (брат преподобного Симеона, Нового Столпника) — 10 мая (27 апреля ст. ст.)St George, brother of Holy Father Simeon, celebrated on 10th May
Святой Георгий, епископ Никомедийский, творец канонов, день памяти — 11 января (29 декабря)St George, Archbishop of Nikomedia, Author Of Canons, celebrated on 11th Jan
So there are, ehem, rather a lot of Saint Georges and Holy Georges in the Russian Orthodox Church
