Quirrell Quandry Achievement IconQuirrell Quandry – 15G

Defeat Quirrell in the Quirrell boss fight, using Voldemort

Or you can use Ron to kill the larger spiders on the level Follow the Spiders.

(Thanks and credit go to darthmaulian for this piece of advice)

There are several spells that can be bought from a shop in Diagon Alley, one of those is Glacius. All jinxes can be found at the top of the wheel that shows your spells. You need to hit 20 people with the Glacius to get the achievement.
If you are struggling to get this achievement it might be worth buying Glacius before any other spell so you have more chance of hitting a character with this one because the jinx spells you have bought rotate through.

Role Reversal Achievement IconRole Reversal – 15G

Defeat Harry (as Voldemort), in the Graveyard
When you have unlocked Voldermort you need to kill Harry at the end of the level “The Dark Lord Returns”. To do this you may need to use 2 controllers (and maybe have someone play along with you) or you can switch between characters at the end of the level so you can make sure one caharacter is Voldermort and the other is any version of Harry. To kill Harry you must use Voldermort’s Avada Kedavra spell. This is the green one on the spell wheel, just right of the top one.

Quiet Please Achievement IconQuiet Please! – 15G

Turn the sound and music down to 0 in the options menu whilst in the library
When free roaming around Hogwarts, go into the library then open the menu and go to options. Turn the volume all the way down to 0 and turn off the music. Go back out of the menu and the achievement will unlock.
A map will be added here soon to help with finding the library if you are having trouble.

Muggle Trouble Achievement IconMuggle Trouble – 15G

Defeat 10 enemies with a Muggle character
There are several muggle characters that can be unlocked throughout the game. When you have unlocked one, go into any level that regenerates enemies (such as the
Forbidden Forest) and get the muggle to hit the enemies by pressing the B and kill them. Do this to 10 enemies and the achievement unlocks.

Lumos Solem Achievement IconLumos Solem – 15G

Destroy 50 Devil’s Snare plants
This achievement is best to go for as you play through. As the title suggests you must use Lumos Solem on 50 Devil’s Snare plants throughout the game.
If you get to the end and still do not have the achievement then play through any level that has a lot of devil’s snare on it, such as the Forbidden Forest, and run through destroying them. I don’t think you will need to though because I have played through twice and both times I got it while playing.

Quick Quidditch Achievement IconQuick Quidditch – 15G

Complete the Quidditch level within five minutes
You must run through and complete “A Jinxed Broom” in under 5 minutes. This is can be done alone with a bit of practice but is easier if you can get someone to use a second controller and run through with you.

Ghostly Treasure Achievement IconGhostly Treasure – 15G

Collect 500 ghost studs
When playing through on story mode you can get Nearly Headless Nick to show you where you need to go by leaving a trail of ghost studs. Collect 500 of these for the achievement. (You do not need to have “Collect Ghost Studs: unlocked to get this achievement)
