Google is a start point on the startup item name or the file name at the end of the location.
However 27 is extra ordinary, there are only 6 in mine.
There are many applications that on installation want to run on startup, unless it is a security or absolutely essential you should be able to uncheck some after investigation.
You could post a screen shot of some that you are unsure of, expand the columns to see the file name in the Command column, see image.
