Harry kisses Cho Chang and Ginny Weasly.
In the book he kisses Ginny in her room before being walked in on by Ron and Hermione. In the film he kisses Ginny in the Burrow kitchen before noticing that Fred is watching them :)
Yes, he kissed Cho Chang in the 5th book, and Ginny several times in the 6th and 7th books.
Yes, Cho Chang did try and take Harry to the Ravenclaw common room to look for the Lost Diadem in Harry Potter and the Deathly Hallows however Ginny was unhappy about this and suggested that Luna Lovegood took him.
First Harry kissed, Cho Chang. And then later on kissed Ginny Weasley. Later Ron and Hermione kiss. But I believe that is all of them.
Ginny Weasley.
He married Ginny and had children with her.
The fanfiction you are referring to is likely "Jealousy (A Cho Chang Story)" by Frozenlight22. In this story, Cho struggles with her jealousy towards Ginny after Cedric chooses her as his treasure for the Triwizard Tournament task. This jealousy complicates Cho's feelings for Cedric and leads to a confrontation between the characters.
They barely know each other but in the final book Cho offers to take Harry to the Ravenclaw common room and Ginny pointedly says that Luna will do it because she doesn't like Cho's intentions.
Ginny Weasley and in their fifth year Cho Chang.
Ginny Weasley, Cho Chang (only once did they kiss)
Cho Chang and Ginny Weasley.
In the movies I think Hermione likes Harry then Cho Chang then Ginny.
Ginny Weasley. Cho Chang and Romilda Vane used to like him.
No, he likes Cho and then Ginny but never Luna
First, he likes Cho Chang, then he likes Ginny Weasley(Ron's little sister), but he ends up marrying Ginny.
Ginny Weasley and Cho Chang are not places, so I'm guessing your asking who are Ginny and Cho. Ginny Weasley is Ron Weasley's younger sister. She is the youngest Weasley and the only girl. In the epilog of the last book/movie, she marries Harry Potter. Cho Chang first appears in the fourth movie, Harry Potter and the Goblet of Fire. She is Harry's first love interest, but is dating Cedric Diggory through out the movie/book. When Cedric is killed at the end of the fourth movie/book, Harry briefly dates her. After the fifth book/movie, she is no longer an important part of the series.
