Context: A complete overview of the supernova remnant (SNR) population is required to investigate their evolution and interaction with the surrounding interstellar medium in the Small Magellanic Cloud (SMC). Aims: Recent XMM-Newton observations of the SMC cover three known SNRs (DEM S5; SNR B0050-72.8; and SNR B0058-71.8); which are poorly studied and are X-ray faint. We used new multi-frequency radio-continuum surveys and new optical observations at H; S ii; and [O iii wavelengths; in combination with the X-ray data; to investigate their properties and to search for new SNRs in the SMC. Methods: We used X-ray source selection criteria and found one SMC object with typical SNR characteristics (HFPK 334); that was initially detected by ROSAT. We analysed the X-ray spectra and present multi-wavelength morphological studies of the three SNRs and the new candidate. Results: Using a non-equilibrium ionisation collisional plasma model; we find temperatures around 0.18 keV for the three known remnants and 0.69 keV for the candidate. The low temperature; low surface brightness; and large extent of the three remnants indicates relatively large ages. The emission from the new candidate (HFPK 334) is more centrally peaked and the higher temperature suggests a younger remnant. Our new radio images indicate that a pulsar wind nebulae (PWN) is possibly associated with this object.Conclusions. The SNRs known in the SMC show a variety of morphological structures that are relatively uncorrelated in the different wavelength bands; probably caused by the different conditions in the surrounding medium with which the remnant interacts. © 2008 ESO;
