Is it possible to lose your Aura Bow from your Bag in Pokemon Mystery Dungeon Explorers of Sky?

Answer 1

Yes, because your bow increases the power of your team when you have it so it is bad if you lose the bow you start off with (if it is a friend bow, that does not matter as much because it only increases the recruitment rate by 10 percent)

Answer 2

Yes, if you are defeated in a dungeon, you will lose some items from your bag. Any item can be lost.
