Mandatory members in an RPA architecture?

I have the following questions my spoken English is not very good and I have not been able to understand the following points:
What are mandatory members in an RPA architecture?
How can I see the history of robot executions in the Orchestrator?
What is the sign that is used as a wildcard in a selector?
Which Version Controllers are natively supported by UiPath?
What data does a Publication to Orchestrator request in a required way?
Where are the projects that we load to the orchestrator shown?

what a pity if my English is not very good I am trying hard to learn and would appreciate your help.
