One simple way would be to insert a line with:
Call Macroname
as the last line of the first four macros, where Macroname is the name of the next macro.

Another way, which you allow you to continue running the independently if you wish is to create another macro like:
Sub Main()
Call Macro1
Call Macro2
Call Macro3
Call Macro4
Call Macro5
End Sub
