As shown in the last photo, 4 of your 5 items are medical ampules. In other words, mid 20th century medical waste.
The bulb shaped glass object appears to be a light bulb. I cannot tell from your photos but you should see some type of glass stem inside which supported the bulb's leads and filament.
While these objects have no value, dumps of this era still can contain items of value (for example milk and soda bottles). It is also possible to find earlier objects that were tossed in with this trash.
