Can I use root used to create multiple BIP32 addresses, to spend transactions belonging to these multiple BIP32 addresses?
A BIP32 master extended private key can be used to derive child addresses, but to spend coins sent to those child addresses, you will need the private key of each individual address. The master xpriv key cannot spend the coins located in one of its child addresses. 

Remember that an address derived via BIP32 is otherwise indistinguishable from any other address. In order for a transaction spending any address' balance to be valid, it must be signed by the private key of that address. 

That said, good wallet software will take care of key management in the background for you, so as long as the derivation scheme is correct you should be able to spend the funds sent to your master xpriv key's derived addresses using a BIP32 &amp; 39 compatible wallet. Again, this will be done by deriving the child addresses and using their private keys to sign transactions.
