Detailed explanation-1: -Excel absolute cell reference (with $ sign) The dollar sign fixes the reference to a given cell, so that it remains unchanged no matter where the formula moves. In other words, using $ in cell references allows you to copy the formula in Excel without changing references.

Detailed explanation-2: -On the Home tab, click the Dialog Box Launcher next to Number. Tip: You can also press Ctrl+1 to open the Format Cells dialog box. In the Format Cells dialog box, in the Category list, click Currency or Accounting. In the Symbol box, click the currency symbol that you want.

Detailed explanation-3: -A mixed reference uses a dollar sign either in front of the row letter or in front of the column number, but not both – for example, A$1 is a mixed reference in which the row adjusts, but the column does not.

Detailed explanation-4: -If you’re typing a formula, you may sometimes want a cell reference to stay locked on a specific cell or cell range even if the formula is copied. To do this, you’ll need to change the cell reference to an absolute reference by adding dollar signs before the row and column (for example, $D$2).
