What fish can i put into a fish only salt water fish tank?

Ok so this is the deal i've been doing freshwater tanks for 2 yrs now i can't afford a mive salt tank which obviously is easier (55 gallons or up) but i'm gonna do a 10 gallon nano fish only salt tank. I have live sand and rock from my friends already established fishtank he's got like 5 salt tanks and he even said he'd give me 5 gallons of water from his tank as well so that basically the tanks cycling process will be a few weeks less then it needs be basically this is what i wanna put in the tank. I'm gonna get 2 yellow tail blue damsels to start the tank after 2 weeks of the tank being set up from there i wanna get a puffer fish of some type i know that most if not all get to be 4 to 5 inchs plus but really he'd be the only top water fish and the one i'm looking into after having the tank set up for a few months is a stars and stripes puffer fish as they get to 5 inchs and the 2 damsels will stay small like 1.5 inchs and i'd get the puffer small 2 so he'd grow slowly bigger in the tank i'm also gonna get this package from petco called the cleaner package basically its a mix of every kind of salt water tank critters from snails to crab to shirmp to hermit starfish and other things but i can't remember what else it is but i was told thoose types of things don't matter in a fish tank as to causing imbalances like fish do. But thats my idea and after the damsels die i was contemplating a dragon wre and a filimented flasher wre. will this work out or not and if not can anyone suggest any better ideas i realllllllly want the puffer and idc if he was the only fish in the tank
