What are the specific naming conventions for variables in bash shell scripting language?

Question

Is it the same convention as those used in known programming languages such as Java and C? I'm trying to create a lot of variables and I want it to start with a number, but I'm not sure if it's okay.

According to The Open Group a variable name may not start with a number.

A valid variable name start with a letter capitalized or uncapitalized. The following characters can be letters, digits or an underscore (_).
