I don't think so. TPI is batch injection and MPI is sequential injection.
I could be wrong about what MPI is, but I always thought it was sequential.

Generally speaking, Yes, but neither of these terms indicates when the injector is fired.
All thirdgens are batch fire; MPI (Multi Port Fuel Injection; MPFI) in general only indicates where the injector is located, which includes the TPI.
Sequential is SMPFI, or SMPI, yet most just say SPI.
