Should I add a new column headers to Outlook contacts?

[Davi]

Should I add a new column headers: One of my friend incoming contact from
website to Outlook contacts

One of my friend incoming contact from website, so I can contact him in that
website (although I have his email address)

For example
He contact from website.com

Should I add a new column headers: Incoming Contact From Website?

This will help me to contact him by that website if he lost the email address?

I can open Outlook Contact to add this contact.
But I don't know how to add a new textbox "Incoming Contact From Website".

Can I use other Office applications to better manage the information?

I have many contacts in many email accounts, texts, etc.

There are many key words, my friends contacts in many email address, and
text, I need to send all these contacts in an email to one email address,
which keywords I should include in the email content or subject? So I can
search the Gmail Inbox.
I have a gmail account.

Can I use Office applications? Which application I can use?

Remember, in gmail address book:
Name
Main email address:
Description:
Picture:
Personal Information
Email:
Tel:
Address:

Work
Email:
Tel:
Address:

And I can add many information textbox.
