After dealing with a cross country move and getting settled in our new place, I realized that I'd forgotten to keep the tires in our 2 road bikes inflated.

All 4 tires are essentially flat but we'd like to get out and ride this weekend if possible.
I'm not a wiz at bicycle maintenance so I would appreciate any feedback on tips for reinflating the tires so I don't get a buldge or pinch flat.
