Where are the quotes in a bubble on my LG G3 Status Bar?

LG G3 Status Bar

Left status bar shows 3 icons: quotes in a bubble, box with "ID", and a lock. What are they?

Quotes in a bubble... that's probably Hangouts.
Box with ID and the lock, not sure.

But any icon on the top left corresponds to an active notification. Dragging down the notification shade should show you the apps that have posted something.
