Okay, I'm a 17 year old bass-baritone singer, and clearly as you can tell from me being on this site I love musicals. My range is about F2 to about F or F#4 but notes above middle C# for the most part are very high not something I could use in a conversational way although my F4 is a good top note in a song. I want to know what relatively large parts I could sing other than Javert and The Beast. I totally realize that I could sing in the chorus but I would like to think there are other low parts out there.

Well, there's the bishop. He's got some lovely low notes.

Outside of Les Miserables (since you mention the Beast), there's Caiaphas in Jesus Christ Superstar. And also Emile de Becque in South Pacific.

In Les Mis, I think Grantaire can have a lower range.

Omg I didn't mean to post this in the Les Miserables lol, thank you very much I'll look into those.

Well, Caiaphas ain't bass-baritone - he's flat-out bass. Bunch of low Ds and a C-sharp.

But the golden age of musical theatre has a ton of stuff. The Captain in "The Sound of Music" is a bass. Miguel de Cervantes/Don Quixote in "Man of La Mancha" is a baritone, can be sung by a bass-baritone. The Innkeeper in the same show is also a bass.

Most of the male roles in the Gilbert & Sullivan canon are baritone parts, too.

Sweeney or the Judge maybe?

Most of the roles that Shuler Hensley played are bass-baritone :

-The Monster (Young Frankenstein)
-Kerchak (Tarzan)
-Jud Fry (Oklahoma)

Ahh, wish you'd asked this in one of the general forums, I almost missed it. Good low male roles:

The Pirate King (The Pirates of Penzance)
The Mikado (The Mikado)
Audrey II (Little Shop of Horrors)*
Judge Turpin (Sweeney Todd)
Sweeney Todd (ibid.)
Cervantes/Don Quixote (Man of La Mancha)
Tevye (Fiddler on the Roof)
Jud (Oklahoma)
Pharaoh (Joseph...)

Now, those are roles that all essentially require a bass or baritone with a good lower range. There's also a set of baritone parts that typically use a lighter tone but don't have a particularly challenging high range like The Baker (Into the Woods), Horton (Seussical), and Curly (Oklahoma) so work on being able to sing with a brighter tone when needed (I call it my "Baritone Emulation Mode").

*This is WRITTEN a bit higher in the score, but the movie version was interpreted in a bass-baritone range, so if you interpret it the same way, nobody will be surprised or complain.

A lot of the "Golden Age" shows have lower baritone leads. The Captain in The Sound of Music is, Emile de Becque in South Pacific, Hapgood in Anyone Can Whistle, etc.

Other parts I can think of:

Officer Lockstock and Cladwell in Urinetown
The Reciter, Soothsayer, Russian Admiral, and Kayama in South Pacific
Booth, Czolgosz, Hinckley, and the Proprietor in Assassins
Ben in Follies
Mack Sennet in Mack and Mabel

Thanks a lot all of you these roles are great. My vocal range is expanding now and these songs are perfect
