Absolutely, the protocol always refers to a channel by its short channel ID (blockheight, transaction pos, output pos). So a single transaction can fund multiple channels. I should however mention that this is currently not implemented in any of the wallets, but it shouldn't be too much of a problem to do so. The main problem is that in order to use this you need to coordinate the fund-channel process for all channels in parallel, so initially it's probably only going to be used to fund channels from a single initiator.
