One of my friends used my wallet to import a funded blockchain wallet to my wallet id. First this wallet is watch-only and I can't spend the bitcoins inside this wallet because I need the private key. Is it possible to recover private key from the address of this imported wallet ?

No. You don't have the private key(s) for the wallet and you do not have enough information to get them. The Bitcoin isn't yours anyways.
