Can I open many channels to one connection?
he commands above transfer money the BITCOIN NETWORK to the LIGHTNNG NETWORK - right???


No. It sends money to addresses the c-lightning can use for creating Lightning Network transactions. There is no "transfer money from Bitcoin to Lightning", they are not separate and distinct things.


  If so, which BITCOIN "FROM" address is being used?


There is no such thing as a Bitcoin from address. That is not how Bitcoin works. It may seem like there are from addresses, but that's just a simplification for users.


  Is what I would like to do possible?


No, it is currently not possible to choose what transactions to use to fund your channels with c-lightning.
