Can a macro be self-starting based on some event?

Events such as:
1) opening the file
2) preset time
3) value of certain cell contents

Trying to set a spreadsheet to run a series of queries and macros every
night.

Also hope to learn if i can set up a series of queries and macros to run in
sequence whether autostart or not.

Could these macros run even if the Excel file is not open?

#1. You can use a sub named: Auto_Open (placed in a General module)
or you can use the Workbook_Open event in the ThisWorkbook module.

#2. You can use application.ontime to start a macro when you want.
Chip Pearson shows how:

#3. If the value changes because of the user typing something, you can use the
worksheet_change. If the value changes because of a formula recalculating, you
can use the worksheet_calculate event.

If you're new to macros:

Debra Dalgleish has some notes how to implement macros he

David McRitchie has an intro to macros:

Ron de Bruin's intro to macros:

(General, Regular and Standard modules all describe the same thing.)

Chip Pearson has some instructions on events:

David McRitchie has some notes, too:

There are application events, too.
