Exclamation Help me out with this

Say that there are three friends who went to a restaurant, where they can choose 5 dishes. Three of each only choose 1dish. How many different orders can the waiter take?

I don't understand. If any combination is possible, the answer is 5*5*5 = 125. If three different dishes must be ordered, the answer is 5*4*3 = 60.

I don't understand what "three of each only choose 1 dish" means. What do you mean by "three of each".

Are two orders considered different if they consist of the same dishes, but differently distributed amongst the three friends? Does each friend choose at least one dish? If a friend chooses, say, two dishes, can those dishes be the same? How many of the three friends choose only one dish? How many different dishes are available at the restaurant?
