Do these character names sound alright?

I'm working on a book right now, and I wanted to know if you all thought these character names sound good, as far as their phonetic flow and the image they conjure of the character.

The book is a fantasy parody, so the names aren't "normal"; if some of them sound absurd, ridiculous, and idiotic, it's because they're supposed to. The names are below:

Septimus Octavian Nines (Tim for short)

Salem Yorik Garm

Snookeroo Elias Garm (Snook for short)

Heather Hather

Beulah Phott

Nancy Krimlin Crummies

Smithe Sommers

Silas Algernon Longue

Dr. Rigel Jones

Col. Sinclair Richards (nicknamed Leggy)

Altor Calchas

Sgt. Iago Insurgo King

Magna Carta King (Maggie for short)

Nathan Faust Moore (Nate for short)

Linnea Hadgebak

Junius Kraken

Virgil Grimshaw

(Note: the characters with the long names are the ones that have middle names; the second name is rarely mentioned.)

All input is welcome. Thanks, everyone!
