There - States a place of being. Shows that something is at a place and is telling the reader/listener where something is held or placed.

Their - A form of ownership. Something that they have with them, replace their with a name or proper noun. You could say, "I like Mike and Julie's dog." But with their, you could say, "I like their dog." It could show one or more than one person's ownership, whichever pronoun (he, she [singular], they [plural] needs it.

They're - A contraction meaning, "they are". If you want to make a sentence using this, make sure the there/their/they're that your using reflects upon who your talking about. Make sure saying "they are" makes sense within the sentence before you place it there.
