CraftSessionId

Craft relies on PHP sessions to maintain sessions across web requests. That is done via the PHP session cookie. Craft names that cookie “CraftSessionId” by default, but it can be renamed via the phpSessionId config setting. This cookie will expire as soon as the session expires.

*_identity

When you log into the Control Panel, you will get an authentication cookie used to maintain your authenticated state. The cookie name is prefixed with a long, randomly generated string, followed by _identity. The cookie only stores information necessary to maintain a secure, authenticated session and will only exist for as long as the user is authenticated in Craft.

Provider: this site. Expiry: Persistent.

*_username

If you check the "Keep me logged in" option during login, this cookie is used to remember the username for your next authentication.
