So in my code I used
function $(id) {
return document.getElementById(id);
}
I want to move to jQuery. How to translate such thing to it?

Don't use this function, function $(id). Use the jQuery function $('#id'). This function will return an object with bunch of jQuery methods.
Methods include remove(), hide(), toggle(), etc., and the implementation is like $('#id').hide(), $('#id').show(), etc.
There are so many, many jQuery methods, that simplifies it in so many ways.

If I got your question right, you will need to include jQuery inside your page, and replace the following line:
return document.getElementById(id);
with this one:
return $("#"+id);

Oh no, don't make another
$ function, that's completely unneeded.

I'm not doing so, just answering his question. and yes, I agree that he shouldn't use a function called $(id), but I didn't see his full code to assume that he can't use such function.
Using Jquery selectors you can do the same thing very easily.
$("#" + id)

Just use
$("#"+id)
That will return the element with the right ID.
