Yes, I was there today and seen it happen. They do encourage you to register at customer service desk (to make it easier for you in the future) but will provide a discount with proper documentation.
What Kris said is correct.
Previous answers are no longer correct (partially). As of Jan 5th you can't just show your ID at the register for 10% discount. You first have to register on line or at the service desk. After that you will give the cashier your phone number for 10% discount.
Yes
Yes they do.
All Lowe's except veterans ID card 10%
I'm not sure. You could always call them and ask.
