Energies and lifetimes are reported for the lowest 375 levels of five Br-like ions, namely SrIV, YV, ZrVI, NbVII, and MoVIII, mostly belonging to the 4s<sup>2</sup>4p<sup>5</sup>, 4s<sup>2</sup>4p<sup>4</sup>4ℓ, 4s4p<sup>6</sup>, 4s<sup>2</sup>4p<sup>4</sup>5ℓ, 4s<sup>2</sup>4p<sup>3</sup>4d<sup>2</sup>, 4s4p<sup>5</sup>4ℓ, and 4s4p<sup>5</sup>5ℓ configurations. Extensive configuration interaction has been included and the general-purpose relativistic atomic structure package (grasp) has been adopted for the calculations. Additionally, radiative rates are listed among these levels for all E1, E2, M1, and M2 transitions. From a comparison with the measurements, the majority of our energy levels are assessed to be accurate to better than 2%, although discrepancies between theory and experiment for a few are up to 6%. An accuracy assessment of the calculated radiative rates (and lifetimes) is more difficult, because no prior results exist for these ions.
