I would like to use special characters like: -, $ and space for key names of objects (or JSON strings).
Are there any characters that can make a key name invalid or any characters that need to be escaped?

Any valid string is a valid key.
For example, you can even use the " as long as you escape it:
xxxxxxxxxx1
var object = { "Example \"quote\" as a key": 123 }2
3
console.log(object["Example \"quote\" as a key"]); // 123
