Are they traveling on trains and staying in hostel dorms? Are they backpacking?
Mostly reinforce safety - never leave anyone alone. Don't go home with a stranger, don't accept drinks from other people etc. Don't get too drunk and if you do get drunk, stay with your friends. Don't do drugs in foreign countries. Don't try to walk or jump between balconies type thing, don't go out hiking or swimming in the dark. Most misadventure comes from bad decisions...and often involves alcohol.
I found a travel lock and a small combo lock very helpful. I put some duct tape around a pen - great for quick fixes.
They can get a SIM card at the airport if they need a physical one or buy an esim before they go. Having data is also a good safety measure.
What he should pack depends on how he is travelling but he can also get anything he forgets there.
And don't go swimming together and leave your documents unguarded on the beach. My brother did that. They were stolen. Tell him not to pack anything he really needs in a suitcase - it must go in the cabin baggage eg prescriptions, wallet, phone, laptop etc. if he does have prescriptions, be sure to take it in it's original bottle from the pharmacy.
Get him to download Google Translate before he goes.
