Would these fish be okay in my 60 gallon fish tank?

Yes all of these will mix very well. With your 60 gallon tank you need to stay below 60 inches of fish.That 60 inches is full grown size , keep that in mind when you buy your fish. a 1/2" fish in the store can become a 1 1/2" to 3" fish in a few months. You mite want to let your tank cycle with only 4 fish for the first 4 to 6 weeks. After it clears again then you can load it up.
