These systems were initially identified as transiting candidates using light curves generated from the full-frame images of the TESS mission. We confirmed the planetary nature of these objects with ground-based spectroscopic follow-up observations using FEROS and the new PLATOSpec spectrograph attached to the ESO 1.52 m telescope at the La Silla Observatory, and with ground-based photometric observations of the Observatoire Moana, Las Cumbres Observatory Global Telescope and ASTEP. From a global fit to the photometry and radial velocities, we determine that the planet TIC 147027702b has a low-eccentric orbit ($e = 0.13 \\pm 0.05$) with a period of 44.4 days and has a mass of $1.09^{+0.07}_{-0.13}$ M$_J$ and a radius of $0.98 \\pm 0.06$ R$_J$. TIC 245076932b has a moderately low mass of $0.51 \\pm 0.05$ M$_J$, a radius of $0.97 \\pm 0.05$ R$_J$, and an eccentric orbit ($e = 0.43 \\pm 0.02$) with a period of 21.6 days. TIC 87422071b has a mass of $1.29 \\pm 0.10$ M$_J$, a radius of $0.97 \\pm 0.08$ R$_J$, and has a slightly eccentric orbit ($e = 0.12 \\pm 0.07$) with a period of 11.3 days. These well-characterised warm Jupiters expand the currently limited sample of similar gas giants and provide valuable benchmarks for testing models of giant-planet formation, migration, and tidal evolution.</summary>\n    <category scheme='http://arxiv.org/schemas/atom' term='astro-ph.EP'/>\n    <published>2026-02-24T07:57:48Z</published>\n    <arxiv:comment>revision version submitted to A&amp;A</arxiv:comment>\n    <arxiv:primary_category term='astro-ph.EP'/>\n    <author>\n      <name>Pavol Gajdoš</name>\n    </author>\n    <author>\n      <name>Rafael Brahm</name>\n    </author>\n    <author>\n      <name>Lorena Acuña-Aguirre</name>\n    </author>\n    <author>\n      <name>Matías I.
