There's a hint on all of them:
- I love ENTERtainment (Regretful Pyramixed Reference: enter.)
- Who's page are you on? (JUST LOOK AT MY DISPLAY NAME!)
- Who's a good Simon? (Hint: The Mons)
- It's not Sprunki without... [Hint (It's a mod): Sprunki with... / Who created the Sprunki Remix mod?]
Based on these hints, I'm pretty sure you'll be able to get the rest.
