In QGIS, I need to calculate the distance between certain points and save this information as a line shape file, in which the attribute of each element (line) is its length (distance between points).

For this I have created a temporary draft layer of lines to draw the lines and I have obtained this:

Now, how do I calculate the lengths and save them as an attribute of the elements?

Open the attribute table of your draft layer of lines and create a new field with the field calculator. Use `$length`

or `length ($geometry)`

to calculate the length of the lines in your layer.
Be careful what you measure: "You need to use a Projected Coordinate Reference System with units of meters or feet to perform such calculations"
