Each of the characters you listed could be considered an example of symbolism, some of which are very obvious. For example, Mr. Summers and Mr. Graves have surnames that are even symbolic; they are in charge of the lottery, which takes place in the summertime and results in a new grave due to the death of the "winner."

...Every year, after the lottery, Mr. Summers began talking again about a new box, but every year the subject was allowed to fade off without anything's being done. The black box grew shabbier each year: by now it was no longer completely black but splintered badly along one side to show the original wood color, and in some places faded or stained.
Mr. Summers' attempts to convince the townspeople to make a new box are symbolic of those in society who consider the lottery important, such as Old Man Warner. However, his prodding does not produce a response. The condition of the black box represents the practice of conducting the lottery, which "some places have already quit."
Tesse Hutchinson may also be an allusion to Anne Hutchinson who was denounced for her rebellious way. She was found to be heretical by puritan society and eventually banished from massachusetts. Now while Tesse had no spiritual rebellion she acts as the protagonist within the story. She was excommunicated despite the unfair trial. And she tried to fight against the system and the town's traditions, breaking out of the traditional role of a humble wife and obedient citizen. Her insubordinaton may have been what led to her 'banishment', and in this case stoning.
