1. Run the jobs on the listed machines by order.

If you want ordering, a DAG is probably the way to go. You can define
each job as a child of the previous, and each job would have the
requirements set to a particular machine.

If you need strict ordering, i.e. job B must not start running until job A has completed, then indeed you want to use condor_submit_dag as Ben suggests.

However, if you just want to tell HTCondor an order in which to start running your jobs as machines become available (note that the order in which HTCondor starts jobs is not the same as only starting a job after a given job completes), you can simply specify a job priority in your submit file like so
  executable = foo
  priority = 5

Job priority can also be adjusted after the job is submitted via the condor_prio command line tool.

Job priority can be any integer, with 0 being the default. Jobs with higher numerical priority will run before jobs with lower numerical priority. Note that this priority is on a per user basis. One user with many jobs may use this command to order his/her own jobs, and this will have no effect on whether or not these jobs will run ahead of another user's jobs. If you want to prioritize jobs submitted by different users, you'll want to use the condor_userprio command.

2. While all the computes nodes don't have the permission to submit jobs,
what do I edit and what do I write to allow the jobs to run only after 9 pm
and on the weekends.

If you want *all* jobs to only run during those periods (and assuming
jobs should stop at 8am), you could define something like this on your
compute nodes:

   IsWeekend = (ClockDay == 0 || ClockDay == 6)
   AfterHours = (ClockMin < 480 || ClockMin >= 1260)
   START = $(IsWeekend) || $(AfterHours)
