Professional music video at home?

At school, we need to make a professional music video in eighth grade (I'm in 7th) I've already started thinking about this and got really excited. My group will probably be 4 or 5 friends depending on what my teachers concept of groups is (friends choose or she picks)
If I'm with my friends i want to make it look pretty professional but still goofy and exciting kinda like Ariana Grande and Mac Miller's song "The Way" music video

do you have any tips?

any apps to use for an iPhone or macbook that don't cost much money but will make it look good? (i have to add music to the video)

any songs without swearing or vulgar language considering my school is Catholic and we'd get an F?

I know what you mean. I go to an all girls catholic high school so I know how strict the teachers can be. I like the app video star, you can change filters and edit your voice, it's pretty g.

A lot of songs these days, or the songs I like, have a lot of curse words. But most of Bruce Springsteen's songs are clean and the song Stairway to Heaven might fit the whole "jesus is my life" motif catholic schools tend to have. Anyway good luck!
