Can a stonecloaker return itself? Will the 2nd ability of removing card in graveyard from the game occur if this happens?

Yes and yes. Stonecloaker needs to come into play for its bounce ability to trigger, which means it's definitely in play when the ability resolves (unless it's removed before the ability resolves). And once an ability has triggered and gone on the stack, removing its source doesn't affect the ability on the stack - once the graveyard-exile ability triggers, no matter what happens to Stonecloaker itself, it will resolve.
