Yes you can but it will cost you about a hundred something dollars a person. If you want Disney merchandise go to Disney springs or shopDisney. Com
Maybe online
Yes you can........ with the purchase of a park ticket
No

Unfortunately, there's no option to enter Epcot just for buying merchandise or food. Disney's Boardwalk has dining areas and some shops.
I don't think so
