We know very little of Kilion (Ruth's husband) from the narrative and certainly not enough to know if he and Boaz were close friends. However, since Boaz was very familiar with Naomi, Kilion's father, it stands to reason that they were probably friendly, but there is no certainty in this.
Through marriage.
1) Ruth's father-in-law, Elimelech, was a relative of Boaz.
2) Ruth herself later married Boaz.
Obed is the only son of Ruth and Boaz, it is in Ruth chapter4.
Boaz was Naomi's relative through her deceased husband's family. He was a kinsman-redeemer who had the right to marry Ruth, Naomi's daughter-in-law, and redeem the family property.
She started by gleaning in his field, to feed her family (Naomi)(Ruth 2:2 - Ruth 3:11). Boaz heard from others what a fine woman she was, hardworking and kind, and she spoke with Boaz about her situation and finally slept at his feet one evening(Ruth 3:14-15) after finding out that he was a distant relative of Naomi's and a 'repurchaser'. Basically her attitude and fine qualities drew Boaz's attention.
Fom the line of Ruth and Boaz.
Ruth/Boaz. Boaz is called a kinsman-redeemer, a person who buys, redeems, takes back, something/someone into a family.
The rising action in the book of Ruth includes Ruth's decision to stay with Naomi, Ruth's gleaning in Boaz's field, Naomi's plan for Ruth to approach Boaz, and the development of Ruth and Boaz's relationship. These events set the stage for the climax of the story.
No. Tradition states that Boaz died shortly after marrying Ruth, and they had a single son. See also:More about Ruth

Boaz (Ruth 4:13)
Yes Ruth and Boaz were related to Jesus.Ruth is the great, great grandmother of David.
Boaz died after he married Ruth, and had a child as well but when he died the bible does not say.
The great grandparents of King David were Boaz and Ruth. These are the same Boaz and Ruth that are the main characters in the Book of Ruth.
