6) Can I reprint my boarding pass if it's lost or damaged?

Yes, most airlines will allow you to reprint boarding passes. If you're travelling with TUI, log in to the Flight Extras website and if you've already checked-in, you'll see a print button. Click this and your boarding passes will appear, ready for reprinting. You'll be able to do this up to six hours before your outward flight, or up to 25 hours before your return flight. You'll need to print each boarding pass clearly on an individual piece of A4 paper. 

If its later than this and you need a new copy of your boarding passes, you can collect them from the TUI bag drop desk when you arrive at the airport.
