Yes that makes 10 Muse sonnets, as Shakespeare offers the fair young man the role of tenth muse in sonnet 38!

The 9 Muses: 

are the protectors of the arts and sciences and are often called upon by poets for inspiration. If Shakespeare can conclusively to have believed in any supernatural spirits, it was these nine, who could only be attended, not commanded. 

Mnemosyne, the mother of the Muses was a female Titan.

Her daughters were conceived over 9 nights with Zeus:

Calliope, the chiefest Muse and muse of epic poetry. Her emblem is the writing tablet.

Euterpe, the Muse of music. Her emblem is the flute.

Clio, the Muse of history. Her emblem is a scroll and books.

Erato, the Muse of lyric poetry and hymns. Her emblem is the lyre and a crown of roses.

Melpomene, the Muse of tragedy. Her emblem is the tragic mask.

Polyhymnia, the Muse of the art of mime and sacred poetry. Her emblem is a pensive expression.

Terpsichore, the Muse of dance. Her emblem is dancing with a lyre.

Thalia, the Muse of comedy. Her emblem is the comic mask.

Urania, the Muse of astronomy. Her emblem is the staff and celestial globe.

A mnemonic phrase for remembering the Muses is:

Carol Eats Crumpets, Even More Plump Teas Than Usual.

Here are the naughty spirits named.

The 9 bad spirits:

First are the false gods of the gentiles with idols and oracles, e.g. Delphi whose prince is Beelzebub.

Second are liars and equivocators like Apollo Pythius and the like;

the third are those vessels of anger, inventors of all mischief and whose prince is Belial;

the fourth are malicious revenging devils whose prince is Asmodeus;

the fifth sort are cozeners such as belong to magicians and witches and their prince is Satan.

The sixth rank are devils of the air and corrupt the air and cause plagues, thunders and fires etc as spoken of in the Apocalypse, their prince is Meresin.

The seventh is a destroyer, captain of the furies, causing wars, tumults, combustions, uproars, also mentioned in the Apocalypse and called Abaddon.

The eighth is that accusing or calumniating devil that drives men to despair.

The ninth are those tempters in several kinds, and their prince is Mammon.
