What are the specific differences in usage between SN74AXC4T245-Q1 and TXB0104-Q1, and can they be replaced with each other?

    They use completely different architectures.

    The TXB does not need direction-control signals, but has restrictions on the minimum drive strength of other devices and on the maximum output load. In general, you can use the TXB only for direct connections between two other, nearby chips.
