This is not possible, try asking the person with a tweet (to send a message directly to someone type @<twittername> before your tweet, however it will still be public, I think). To request to follow someone with a private account, click on follow and a message will be sent to them to either accept or deny your request.
You cannot send a friend request on Gmail. Instead you can send a chat request. It means the person is inviting you to chat.
