How do I sync my contacts with yahoo & gmail?

[Loc22]

I just got my iPad air & I'm trying to set it up so that my contacts will sync with my other devices & I will always be updated with the latest version.

I currently use a Blackberry Z10, PC & my new iPad. My Blackberry & my PC sync my contacts with 2 yahoo accounts, 2 Gmail accounts, Facebook & LinkedIn. While setting up my iPad I realised I can only sync my contacts with 1 yahoo account & that's it. How do I sync to the rest of the accounts as well at the same time?

you should still be able to add the second yahoo account-
