Cleaner shrimp and peppermint shrimp are fine together, or they are at least in my current tank. My Coral banded shrimp was a big bully. Went after everything that came near its cave. Finally got rid of him when he grabbed a coral beauty by the nose and started shaking it.
Gobies I can just give you advice on the few that I have or have had.
Yellow headed neon sleeper goby- not unless you have a very established tank. Had 2 starve, not enough research before I bought, bad me.
Diamond goby- great sand sifter, committed suicide 2 days after. Love to jump.
Dragon Goby- My personal favorite sand sifter. Not as flashy as some, but does a great job cleaning the sand and seem pretty hardy.
Hope that gives you some help. Like I said, just personal experience.
