Last night i purchased realm transfer to Mograine and transaction was on pending status and when i woke up i see transaction complete but when i enter my char it says error char transfer “the selected realm is not accepting char transfer at this time”
That’s correct. Mograine transfers has been blocked off, see this thread:
If you have troubles with logging in the character at your current realm, open up a ticket to get it looked at.
i saw that but when i made the purchase it was still available.Also after real transfer can i change faction ?
No, there is no faction change in classic
