Looks good, about the license, for a commercial usage, if a game is profitable that uses your sound effects here, do you require royalties? or is the $5.00 USD the only compensation you are requiring?

just the $5.00 is fine! or if you received the sound effect pack in a bundle, that works too. no royalties required.
and, hey, if your game makes it big (and you're feeling generous), i'd be open to donations. but no pressure, just whatever you or your team are comfortable with.
best of luck with your game!
