The first word is still in use, but is somewhat rare and almost always appears in compound words, e.g. 不倒翁，仙翁. The second word is almost dated. I only see it in the menus of some (few) restaurants as a measure word.

翁 refers to 1. an old man, 渔翁、仙翁 2. respectfully call one's father, 家翁(my father)、令尊翁（your father）、翁姑（husband's father） 3. respectfully call an aged man with 翁 following his family name, 苏翁（周星驰的《苏乞儿》，搞笑的称呼） 4. a family name, e.g. a Hongkong actress called 翁美玲, a singer called 翁倩玉 盅 refers to a container which is like a little jar. It is quite a daily word to me who live in Guangdong for it's highly frequently used in our breakfast store here, 炖盅、盅汤 are both mean the soup in 盅.
