You broke the lugs
while the car was still on the ground, so they should be pretty easy to remove. I like to remove them from the bottom up, leaving the top lug nut to be removed last. This keeps the wheel in one place while you remove the rest of them and makes it easier to safely catch the wheel once you remove the last nut. You can't replace brake pads with the wheel on!
If you remove the lugs and still can't get the wheel off, try this stuck wheel trick.
