Q: I want to put gmail  in apple id and icloud

Howdy there RossN,

It sounds like you want to either change your Apple ID email address to this Gmail account, or you want to add it as an additional or rescue email address. If you want to change your Apple ID email address to this email, use this article:

Change your Apple ID - Apple Support

If you want to add it to your account as an additional email address use this article:

About your Apple ID email addresses - Apple Support

Additional email addresses

Many of us have more than one email address that friends and family use to reach us. Add an email address that you commonly use to your Apple ID account, so people can easily find and communicate with you on Apple services like FaceTime, iMessage, Game Center, and Find My Friends.

To add an additional email address, follow these steps:

1. Sign in to your Apple ID account page.
2. Click Edit in the Account section.
3. Under Reachable at, select Add an Email Address.
4. Enter your additional email address and we'll send a verification to that address. Didn't get the email?
5. Enter the verification code and click Verify.

If you want to delete one of your additional email addresses, click  next to the address.

If you are trying to set it up as a rescue email address use this section of the same article:

Rescue email address

Having a rescue email address is optional but recommended. If you ever forget your security questions, you can use your rescue email address to reset them. If you don't have a rescue email address, you'll need to contact Apple Support for help. We’ll also send any account security-related notifications to your rescue email address. 

Follow these steps to add or edit a rescue email address:

1. Sign in to your Apple ID account page.
2. Click Edit in the Security section. You might be asked to answer one or more security questions before you continue.
3. If you want to add a rescue email address: 
    
   • Under Rescue Email, click Add an Email Address, then enter your rescue email address. We'll send a verification to that address. Didn't get the email?
    
   • Enter the verification code and click Verify.
4. If you want to edit a rescue email address: 
    
   • Select Change Email Address under the address you want to edit, then enter the new address. We'll send a verification to that address. Didn't get the email?
    
   • Enter the verification code and click Verify.
5. If you want to delete a rescue email address, click  next to the address.

If you use two-step verification or two-factor authentication, you have a notification email address, not a rescue email address. With two-factor authentication and two step verification, you don't need a rescue address. You can also use these steps to add or edit your notification email address.
