As stated, auto-startup can be done from the BIOS using the "alarm" function (if it's provided).
Thereafter, you can use Windows Scheduler to run a Batch File that will run the applications you want in sequence. Each one will start when the previous one finishes. If you haven't done Batch Files before now is the time to learn. They are simple, high-level (plain language), command files running in a Command Window.
The last command in the batch file, after all the other applications have finished, can be the one that shuts down the PC. This differs with the version of Windows. You don't say what version you are running so this as far as we can go at the moment.
If you want a fuller answer, give more information.
