Can each person in a group order their own food or do they have to eat the same thing?

They can order their own but as the portion is extremely huge, you won't be able to finish your own plate

Each person can order their own to share. Each order can roughly feed 2 people.

They only have family style portion to share with the table. Ask the waiter how many items to order for the number of people at your table, they are very helpful.
