Someone Else, Other People
noun
Here you have other and person joined together by the particle の, which shows that "other" is describing "person". So this means someone else or other people. This is more general than 他人, which you already learned. 他の人 can be anyone that's not the speaker, or not the person being talked about. 他人, on the other hand, has an added implication that the person is someone unknown or unrelated.
ほかのひと
This uses the kanji's kun'yomi readings, which you've already learned. As long as you remember those, you should be good to go!
いいよ、他の人にしてもらうから！
Fine, I'll have someone else do it!
え、いらないの？じゃあ、他の人にあげるね。
Oh, you don't want it? Then I'll give it to someone else.
へー、それで他の人をだましたんだ！
Huh, so you deceived someone else!
