The majority of the major attractions at Hollywood Studios are being placed into tier 1, so you can only FastPass one of them.
Now that the 60 day Fastpass+ window has opened for days after Star Wars: Galaxy's Edge opens on August 29, guests have been quick to share on social media the changes to the Fastpass+ tier structure at Hollywood Studios starting from August 29.
Disney began splitting attractions into tiers so it wasn't possible for you to Fastpass+ all the top attractions. For example at Epcot, Soarin' and Test Track are in different tiers so you can only Fastpass one on any given day.
Alien Swirling Saucers
Rock n Roller Coaster
Slinky Dog Dash
Tower of Terror
Toy Story Mania
(And Star Wars Galaxy Edge attractions when they are open to Fastpass)
Disney Junior Dance Party
