We present a detailed study of the massive star-forming region G35.2-0.74Nwith ALMA 1.3 mm multi-configuration observations. At 0.2" (440 au) resolution,the continuum emission reveals several dense cores along a filamentarystructure, consistent with previous ALMA 0.85 mm observations. At 0.03" (66 au)resolution, we detect 22 compact sources, most of which are associated with thefilament. Four of the sources are associated with compact centimeter continuumemission, and two of these are associated with H30{\alpha} recombination lineemission. The H30{\alpha} line kinematics show ordered motion of the ionizedgas, consistent with disk rotation and/or outflow expansion. We constructmodels of photoionized regions to simultaneously fit the multi-wavelengthfree-free fluxes and the H30{\alpha} total fluxes. The derived propertiessuggest the presence of at least three massive young stars with nascenthypercompact Hii regions. Two of these ionized regions are surrounded by alarge rotating structure that feeds two individual disks, revealed by dense gastracers, such as SO2, H2CO, and CH3OH. In particular, the SO2 emissionhighlights two spiral structures in one of the disks and probes thefaster-rotating inner disks. The 12CO emission from the general region revealsa complex outflow structure, with at least four outflows identified. Theremaining 18 compact sources are expected to be associated with lower-massprotostars forming in the vicinity of the massive stars. We find potentialevidence for disk disruption due to dynamical interactions in the inner regionof this protocluster. The spatial distribution of the sources suggests a smoothoverall radial density gradient without subclustering, but with tentativeevidence of primordial mass segregation.
