There is no tx fee paid in coinbase transactions....

I guess he means transaction fees of transactions in the block as block reward.

Can coinbase transaction contains multiple destinations, or does it have to be one output? For example, for the current reward 12.5, if set the coinbase tx to send 10 to one address and 2.5 to another, is it a valid coinbase tx and will it get confirmed by the network?
Yes, you can have a coinbase transaction with multiple outputs. The sum of the outputs just needs to be less than the block reward (block subsidy plus transaction fees).
*Less than or equal to the block reward.

But in reality almost all miner set the outputs (plus fees) is equal with block reward & tx fee Roll Eyes

Also, if OP is interested in technical details, you can see more info at https://www.safaribooksonline.com/library/view/mastering-bitcoin/9781491902639/ch08.html. It's a bit outdated though.

Here's an example one mined by ckpool with 151 outputs including some Segwit ones.

Thanks, another question, can the coinbase output be P2SH address? And can it be segwit?
Yes. The outputs for a coinbase transaction are just like outputs for any other transaction.
