Not that I think it'll do much for you. I'm pretty close to writing Moonglow, and I can't tell you anything more here than there. But I did really want to share them anyways (also I need some faceclaim helps.)

Judith "Judy" Lam
— Momona Tamada

— Found Ciana when she fell from the portal. Promptly decided she was an attacking alien and tried to knock her out with her violin

— It failed. Thankfully

— Judy and her family helped Ciana get adapted to the 1960s. Now they're friends & co-workers

— Big space nerd

— Very offended she can't go to space right now. Get on it, NASA

— Surprisingly accepting of the whole 'saving the world' deal. Really just gave an exasperated sigh and said "fine"

— Ciana is concerned

Susan Botterill
— Kitana Turnbull

— Mom???

— Actually more of a side character, none of them are that dumb

— Fun cameo

Elizabeth Botterill
— Pixie Davis

— Same as Susan, a fun cameo

— I just added a bunch of kids, didn't I? Sorry

Elias Morganstern
— Daniel Brühl

— Rented an apartment to Jess

— Either didn't notice anything weird about Jess, or really needed that money

— Or...

— Nah, probably that. Photography doesn't exactly pay the bills

— When did the Brady Bunch come out, again? That was the 60s...right?

— Eh, who cares

Anthony Lawrence
— John Boyega

— Actually has superpowers. They're called Making Math Interesting

— What I mean is he's an elementary school teacher

— And a math nerd

— Very serious, guys, trust me

— Ha, right. But he tries and, compare to everyone else?

— 100% the guy telling you how stupid you're being while laughing his ass off

— The owner of the local brain cell

— PS: Not Finn being one of, if not the, most enjoyable part of the sequel trilogy. Tones of respect for John Boyega

Darlene Ichikawa
— Lyrica Okano

— Emo Mom Friend TM

—  Unofficially an artist, officially a vet

— Technically she really wanted to be a fashion designer, but it didn't work out

— Knew something was weird about Jess, but kinda just though she was either a weirdo or Russian. Or both

— It's chill, though, time traveling superhero is cool, too
