Friends
Frodo was Sam's best friend growing up. He later became Frodo's gardener but they still maintained a healthy friendship. Later in their adulthood years, Frodo seems to be aware of Sam's feelings for Rose Cotton, seeing he pushed Sam to dance with her. Sam became Frodo's first companion because Gandalf had him go on the journey with Frodo in the first place.Sam later joins the company of the Ring, claiming Frodo is not going anywhere without him, showing his undying loyalty towards his friend. Sam is also the only member of the Fellowship who sticks with Frodo at the end of the film. Frodo's and Sam's friendship is one of the main plot line in the series.

Merry Brandybuck and Pippin Took
The three of them hardly ever interact with each other, but they are proven to have a good relationship. The three of them were the Conspirators, who discussed on keeping the ring a secret and watch over Frodo so he doesn't disappear like Bilbo did. They are all companions in the Fellowship of the Ring. Sometimes, Sam does not like it when they are both in danger or whenever they are causing the trouble. He once snaps, "Trust a Brandybuck and a Took". Merry reflects on Sam's friendship with him and they all wish to see each other again when the Quest is over. Despite being at odds with Merry and Pippin, Sam still considered them to be good friends.

Aragorn
Sam does not trust Aragorn at the beginning, especially of his alias "Strider". He even called Strider "Longshanks and burst into the room with Merry and Pippin backing him up, believing Strider had done Frodo any harm. However, by the end of the Fellowship of the Ring, Sam believes that Aragorn will look after the others as they continue on with their journey.
