Riddle: I'm not the alphabet, but I have letters. I'm not a pole, but I have a flag. What am I?
Answer: A Mailbox. A “mailbox” has “letters,” but they’re mail, not alphabet characters. It also has a “flag,” the small lever you raise to signal outgoing mail, even though it isn’t a pole with a flag. So both clues fit a mailbox through wordplay.
Riddle: It keeps something that cannot be kept, And wakes you when you have slept. It may go slow or stop at times, But even then it chimes.  What is it?
Answer: An alarm clock. “It keeps something that cannot be kept”: Time can’t be held; a clock only measures it as it slips by. “And wakes you when you have slept”: The alarm rings to wake you. “It may go slow or stop at times”: Clocks can run slow or stop (dead battery, mechanical hiccup). “But even then it chimes”: Many clocks still chime or ring on the hour/alarm, even if their timekeeping isn’t perfect. 
Riddle: I hold countless voices that never speak, countless journeys that never move, and ask for quiet to share them all. What am I?
Answer: Library. "I hold countless voices that never speak": This refers to the vast number of books in a library. Each book contains the "voice" (ideas, stories, knowledge) of its author, but the physical book itself is silent. "countless journeys that never move": Books describe "journeys" (adventures, travelogues, fictional quests), but the books remain stationary on the shelves. The reader takes the journey through their imagination. "and ask for quiet to share them all": Libraries traditionally require a quiet atmosphere so that patrons can read, study, and focus on the material within the books without distraction.
