Magpie:
The "Good" Slytherins:

Snape--joined the DEs, accidentally got the girl he loved marked for 
death, vowed to protect her son forever after. Bravely spied on the 
DEs while being completely, loyal to Dumbledore (confining his 
disobedience to tormenting Harry and being unable to teach 
Occlumency). A key player on the good side, but consistently nasty as 
a person. (No effect on other Slytherins.)

Regulus Black--joined the DEs, was horrified (by Voldemort's treatment 
of Kreacher was it?) struck a personal suicidal blow against Voldemort 
which, although ultimately not helpful, was an impressive thing to do. 
(No effect on other Slytherins.) Personality-wise we don't know, as 
he's not a character we ever meet in person. We're told he was bigoted-
-could be one of the many who were all for Voldemort's plans until 
they saw what he was willing to do. (JKR compares Draco to him in 
being attracted and then horrified by the bad side.)

Horace Slughorn--Manipulative collector of people, expresses some 
bigotry, but scared of DEs and allied with Dumbledore. Eventually 
joined the final battle on the good side towards the end after some 
earlier anxiety. 

Phineas Black--Bigoted, Harry seems to consider him obnoxious, but as 
a portrait he's working for the school and the headmaster. We've never 
met him in person.

Not Good Slytherins:

Lucius Malfoy--DE, desperate to get back into Voldemort's good graces, 
though ultimately that came in second to protecting his son.

Narcissa Malfoy--DE-supporter who made a bold move to save her son 
(had Draco been dead, she would not have lied about Harry--tried to 
send Harry to Voldemort earlier). Her agenda coincided with that of 
the good side at a crucial moment.

Draco Malfoy--Really didn't like being a DE, expresses some good 
impulses, but unable to make a definitive move to the good side 
either. 

Andromeda Black--We know she married a Muggle-born, but she does not 
appear in the book except for one scene where she looks haughty, so 
remains "Slytherin not appearing in this book."

Not Slytherin at all:

Sirius Black--Correctly Sorted into Gryffindor (see also 
Tonks/Hufflepuff).

Kreacher--A house elf who changes sides based on who's nice to him. 
Not eligible for any house, as he is one of Hogwarts' many slaves.

Albus Severus--Told by his father he'll love him no matter what house 
he's in, but also that if he doesn't want to be in Slytherin (and he 
doesn't) the hat will not put him there. Not in any house in canon.
