They will be recalculated automatically if automatic calculation is on, which it normally is, and an updated result will be shown. If manual calculation is on then no change will happen until the F9 key is pressed.
You need to have formulas in the cells that use a reference to the single cell you are changing. You can use an absolute reference for the cell in the formulas. Then when you add or change a value in the cell, the table will automatically update itself based on the cell you have changed.
E23 can be a cell reference, referring to the 23rd cell in column E. E23, or any cell reference, can be used in formulas.
Cell references in a formula don't change if they are moved. Relative references will change if they are copied. Mixed references may change, depending on the type of mixed reference and which direction they are copied.
No. Most formulas would not use them. It is used when you want to have a formula that is to be copied, but has a cell reference in it that you don't want to change when it is copied. For a lot of formulas that is not a requirement, so absolute cell reference are only used in some formulas.
A cell reference that does not change when it is copied is called an "absolute reference." In Excel, this is denoted by a dollar sign before the column letter and row number (e.g., $A$1). Using absolute references allows you to maintain a fixed reference to a specific cell, regardless of where the formula is copied.
A relative reference in a formula will change when it is copied.
You use formulas. Formulas can depend on the values in other cells. If you are summing a group of cells, then any change in those cells, will change the total. You can also make a cell exactly the same as another by and equals sign and a cell reference. So if you have a value in cell C10 and wanted cell B12 to show the same thing even when C10 has its value changed, then in B12 you would put:=C10You use formulas.

An absolute cell reference in a spreadsheet (such as Excel) refers to a cell reference that remains fixed when copied or moved. It is denoted by placing a dollar sign ($) before the column letter and row number (e.g., $A$1). This ensures that the reference does not change when formulas are copied to other cells.
Normally it would be a relative address, but depending on what you want to do with the formula, you could have it as an absolute or mixed cell reference. If the cell reference is the same as the cell that the formula is in, you will have a circular reference.
Not exactly. Every cell has an address. When using the addresses in formulas, they are referring to a cell. When a formula is copied, what happens to the cell references differs, depending on the type of cell reference. See the related question below.Not exactly. Every cell has an address.

They can be called a range or a block.
