Depending on the model, many of the LUS hangers can be installed using the SD9 structural connector screw; please see the following link: https://www.strongtie.com/facemounthangersssl_solidsawnlumberconnector/lus-hus-hhus-hgus_productgroup_wcc/p/lus.hus.hhus.hgus#LoadValueswithStrong-Drive%C2%AESDConnectorScrews. Please check with your local Home Depot store regarding availability/ordering of the 500 count cartons. Thank you!
nope. #9 is .177" (about 11/16"). For 1/4" you'd want a #14 screw, more likely labeled as a 1/4" screw.
For the outer face of the OSB you'll want a bugle-head screw that will present a smooth face for the roof covering (tar paper, roofing felt, shingles, etc)
Yes... "Specifically designed to replace nails in certain Simpson Strong-Tie connectors and is the only screw approved for that application. The #9 and #10 SD screws replace 10d and 16d nails, respectively."

No - they would probably split - I use GRK multi purpose screws for that
Not really used for that. These are specifically for Samson hangers. I would use a 3.5" or 4" GRK fasteners. They are expensive but strong as heck.
Yes; A drill/driver was used on recent project utilizing about 400 of the 1-1/2 and 2-1/2 Strong -Tie screws.
