The major purpose of this paper is to investigate the nature of planetary nebulae (PNe) candidates in the southern hemisphere, taken from an internal list. We present spectroscopic observations and imaging of six PNe identified for the first time. Another candidate turned out to be a galaxy. All observed PNe represent evolved stages, their angular diameter ranging from 15$\hbox{$^{\prime\prime}$}$ to 120$\hbox{$^{\prime\prime}$}$, and exhibit very low surface brightnesses. For three PNe indications of interaction with the interstellar medium (ISM) has been discovered.

Key words: surveys -- planetary nebulae: general
