I have created a multisig address

createmultisig 3 "[\"pubkey_1\",\"pub_key_2\",\"pub_key3\",\"pub_key_4\",\"pub_key_5\"]"

I now have a multisig public key "multisig_pub_key"

Would I be right to assume that in order to send funds to the new address, I use the multisig_pub_key?

Can I still continue to send funds to any of the 5 public keys used to create this multsig

Can I also send funds to the multisig_pub_key, i.e. can both the multisig and the 5 pub_keys have value sent to them without causing some form of corruption to the multisig and/or the 5 pub_keys?

How do I spend funds from the multisig, I understand that I need 3 of the 5 private keys, but I do not know how to do that.
