Antique English Death Sermons 1700s / 1800s Mourning Book Parts

I dont know much about these, but I believe that these were part of a book(s) that contained reprints of death sermons given in England. The dates on these include 1774, 1777, 1778, and 1786. These were likely printed later on, possibly in the 1800s. All have yellowed, spots and signs of age. These are from my personal collection; Im just trying to clean out some.
