Linux Need help in making android game

So my friend is making a game for android via tutorials only and not learning any language or software anywhere.
The game has almost completed but there are two problems.
1) How to add music to the game in unity?
2) How to create a popup for restart, go to main menu etc when player dies?

It's a game similar to flappy bird btw

Anyone who can help here?
