3.can we restore public folders ?
Sharepoint/OneDrive:

1.Can we restore mailboxes from a certain point in time?
Yes you can restore the mailbox by using builtin e-discovery option. By the way mailbox are placed in soft deleted for 30 days of deletion date. Afterwards it moved to Inactive Mailbox.You can find the E-discovery option under on Office 365 security and compliance portal.
2.Can we restore messages ? ( not from deleted items)
Yes you can restore certain emails by Advanced E-discovery function.Where you can defined your own custom condition to meet the filter.
3.Can we restore public folders ?
Yes you can restore the public folder by "Last and Found" option.
- 1. No PIT restore! OFFICE 365 doesn’t work this way!
See here how exchange works regarding backup and restore incl retention:
https://docs.microsoft.com/en-us/office365/servicedescriptions/exchange-online-service-description/high-availability-and-business-continuity
https://docs.microsoft.com/en-us/exchange/back-up-email
Regarding sharepoint and OD it works in a similar way with a 2 stage recycle bin and 93 days combined! 30 days for lists and libraries, collection sites etc
MS also backs up the infrastructure 14 days back afaik! You have to contact them to do a restore here

Also, to keep data etc you also use retention here!!

SharePoint use versioning (shadow copies)

Also there is onedrive restore for disaster recovery, also rolling out for sharepoint!
