Five objects in the direction of the SMC with IRAS 12- and 25-micron flux measurements have been identified from near-infrared observations. They have been monitored in JHK and L for 800 d, and optical spectra of two of the three with optical counterparts have been obtained. 00350 - 7436 appears to be a carbon-rich, high-luminosity object. Either it is in an evolutionary stage between a red giant and a planetary nebula or it is an interacting binary. 00554 - 7351 has M(bol) of about -6.0, is a long-period, large-amplitude variable, and is probably near the top of the asymptotic giant branch. 00483 - 7347 has M(bol) of about -7.2 and is also variable on a long time-scale. 01074 - 7140 is identified with HV 12956 and is shown to be an M5e asymptotic giant branch star with M(bol) of about -6.4. The most luminous of the group is 01432 - 7455, with M(bol) of about -8.2; it is identified with the peculiar blue supergiant, R50.
