You are forgetting Leona in your list there.

Now, listing all the supports, their strengths, who matchs up well with them, etc.

(Warning: Massive Wall Of Text Inbound)

Alistar: Due to his innate disruption abilties, Alistar excels with skillshot champions who can aim their abilities where he herds the enemy champions to in lane (Ezreal, Graves, etc), while also being great for defensive plays to peel off enemy aggression, thus helping champions who have positioning problems (Ashe, Draven) and extremely weak early games (Vayne, Kog'Maw). The bull is one of the few supports who can also jungle and gank extremely well, however, so having him played as a support is increasingly rare. That said, a support that functions as both a passive/defensive playmaker as well as a kill lane support is valuable indeed.

Blitzcrank: In his role as a support, any lane will immediately turn into a kill lane. Blitzcrank support has only his knockup for peeling and no sustain for him or his carry, so his defensive plays are rather weak. On the other hand, he's easily the strongest kill lane support in the game. He only has to land one hook to nearly guarantee a kill. Works well with extremely powerful early game champions (Draven, Ezreal, Caitlyn, Corki) as well as champions that like having their enemies yanked out of position (Vayne).

Janna: The queen slut of assists. Mechanically, her favored matchups are almost exactly the same as Alistar, only with more disruption and less repositioning. Take her with any carry, she's extraordinarily beneficial to all of them. Her shield grants up to a B.F. Sword's worth of Free AD as well as a shield to your laning partner, she can CC for early game champions to land their early game damage efficiently, can CC for defensive plays, her ultimate is a total gamchanger in skilled hands, has a slow on cast, and finally her passive gives Movement speed. She's hard to catch, makes her allies hard to catch and kill, and can screw with the enemy team to creat openings as she pleases.

Leona: Chain-stunning machine, can initiate over minions and other players, and her passive grants extra damage. Works best as kill-lane support, particularly great with Corki above all others, due to his low CD ability spam constantly proccing her passive for bonus damage.

Lulu: The quintessential jack of trades. Can slow, shield, CC, grant vision, heal, knockup, she can do everything very well. Not the best at anything, but a great support allrounder, works well with everyone. Particularly good in Solo Queue as her kit doesn't really need the carry to do anything coordinated with you.

Lux: Unorthodox pick, all skillshot making her somewhat less reliable than most, but brings heavy zoning to your lane. Excellent if securing an early advantage, keeps your carry from worrying overmuch about the enemy. Works great with weak early game champions, limited effect for offensive plays.

Nunu: A god damn rage inducing machine. Free harass, pushes the lane (which can be both good and bad), and Blood Boil is one of the best buffs in the game to put on your carry, and chucks it on himself as well. Blood Boil can also be kept on permanently. Harass early game is ridiculous, due to early game snowball damage. Ult may result in accidental kills that could have gone to the carry, but effective slowing tool. Best support for carries that like Attack Speed over Attack damage. Kog'Maw and Kayle love him the most.

Sona: The ultimate Aura stacker. Heal for lane sustain, good poking power, has a movement speed buff. Doesn't particularly need many items to be effective, ultimate is on the same level of gamechanging as Janna's. Fits into just about any team composition, lanes well with everyone.

Soraka: Considered to be the ultimate healbot. Good for mana hungry champions, such as Graves and Corki. Heal falls off as the game progresses, but remains relevant due to the armor buff. Starcall and Infuse are extremely effective harrassment tools. Wish allows her to support every one of her team members from anywhere on the map at crucial moments.

Taric: Ranged Stun, self and ally heal, large armor buff. Graves with this man is one of the strongest lanes in the game. Hard to take down through innate defensive steroids, will rarely need to back due to his passive and heal sustain. Can make defensive plays, but excels in a kill lane.

So yeah, that's all of the characters that are currently played bottom support.
