Hello, SMMAH

You can restore any old information from your old device using previous iCloud backups. This Apple support article will help Restore contacts stored in iCloud on iCloud.com – Apple Support.

If you do not have an iCloud backup of contacts, you can enable Contacts in the iCloud Settings or Preferences on another device associated with your Apple ID.

I hope this information helps you restore your contacts on your new iPhone.

Take care

Since you say "all" have a look at: Transfer data from your previous iOS or iPadOS device to your new iPhone or iPad - Apple Support
