Help, planning a memorial

1)Do I give general id to attendees as opposed to personal number. I have a workplace pro account. 
 2)The service will be 1 1/2 hours, will attendees be able to attend for the full length of the service.
3) Will the attendees type in brower Join zoom meeting, to get access using both Safari and Chrome?
4.  Can I schedule meeting a month in advance?
