Yes.
function name and arguments
When defining your function, do not put any arguments in the definition (e.g. function myFuntion()). Inside the function, you can use func_num_args() and func_get_arg($number) to get the function's arguments.
Commas are used to separate arguments in Excel functions.
Formal arguments are the named arguments defined by the function. Actual arguments are those arguments that were passed to the function by the caller.
values used with a function are called
It shows you what needs to be put into a function for it to work. You can type the arguments directly into the boxes that are shown for the particular function you are using. It is particularly handy for more complex functions that you are not used to working with.
Optional arguments are ones in a function that you don't have to use. The function will still work without them. It will depend on the function you are using and what you are trying to achieve as to when you use them. Check the help on particular functions that have optional arguments and see what they do. Then experiment with them. They usually give extra information or change how the function works or include extra values. Sometimes you will be able to use them, and other times they are not necessary or a default value is taken.Optional arguments are ones in a function that you don't have to use.

If you have the function main()... You can use its arguments to pass information.
Some functions do and some don't. So it depends on which function you use. Some need more information, like ones that are calculating something like SUM or AVERAGE. Others do not need any arguments like the TODAY function which gives the current date on the computer. So for each function you need to check how to use it and as part of that you will have to find out if it uses arguments and the type and amount of arguments it uses.Some functions do and some don't.

Arguments appear in functions and in function calls. Arguments passed to a function are known as actual arguments. The arguments used by the function are known as the formal arguments. In C, all arguments are passed by value, such that the formal argument is a copy of the actual argument.
The AVERAGE function has up to 255 arguments in Excel.
