Five first ones, it's easy (closing the eyes and taking a big breath)
1-steins;gate
2-fate/zero
3-code geass (R1+R2)
4-Ano hi mita Hana no namae o bokutatchi wa mada shiranai
5-fullmetal alchemist: brotherhood (sorry FMA, FMAB's plot is just so far above^^)
Breathing again:
Then, without order
Guilty crown, Soul Eater, Ao no exorcist, d.gray-man
I know, that makes 9, but around 5 shows are battling for the 10th place, so let's say steins;gate counts for 2 ^^
