you might, puffers have individual personalities, some are more aggressive than others. I know many people who keep porky's with lions long term without issues. Puffers are curious, and tend to "sample" their environment with their mouth, just keep a close eye.
Also with your stock list, if your profile is correct and you have a 100 gal tank you will likely need a larger tank because the fish you have produce a large bioload. Any pics of the tank?
