A formula must begin with the equal sign (=).
If you just type G15 into a cell, it is not a formula but just a piece of text. If you put an equals before it, then it will display what is in the cell G15 when you type it into any other cell. =G15 If you type it into G15 itself you will get an error known as a circular reference, because a cell cannot mention itself in a formula.
You can type it while in Edit mode, or click on the cell while typing your formula, which can referred to as point mode.
Functions have a name followed by brackets. So when you have a name followed immediately by brackets, it is a function. On the worksheet it would also have an equals in front of it. In a module it would have the keyword Function in front of it.

Usually the approach is to copy the formula. There are many ways of doing this, so it depends on the situation as to which is the best to use. It is also possible to select all the cells you want the formula to be in before you enter it, and then type the formula into one cell and press and hold the Ctrl key and then press the Enter key. The formula will be entered in all of the selected cells.
No, you do not need to type the dollar sign, commas, or trailing zeros when entering dollar values in cells. You can simply type the numerical value and format the cell as currency to display it with the dollar sign and commas. Trailing zeros are automatically displayed based on the cell's formatting settings.

It doesn't matter, but after it is entered, Excel will automatically convert it to uppercase.
Yes, cell references should be used. It is not necessary to have values in cells before the formulas that are referring to those cells can be typed. So a formula can be created with cell reference that refer to blank cells first. After that you could enter the values and when you do, the formulas will update their results by using the values that are in the cells. A formula does not change if cells are empty or not. So you could type any formula before entering values that the formula will use. The formula may at first result in a zero value or even an error, but will give the correct result when values are entered into the cells it refers to.
