I'll list them from when I started playing:

Ahri - Mage

Viktor - Mage

Sejuani - Jungler, tank

Ziggs - Mage

Nautilus - Jungler, tank

Fiora - AD carry (but melee, not viable in level 30 and ranked play)

Lulu - Support

Hecarim - Jungler, AD bruiser

Varus - AD carry

Darius - AD bruiser

Draven - AD carry

Jayce - AD bruiser, AD carry

Zyra - Mage

Diana - Mage, jungler

Rengar - Jungler, AD bruiser

Syndra - Mage

Kha'zix - Jungler, AD bruiser

As with most (if not all) junglers, they are also viable in a lane, normally top lane, but for example Diana mid lane.
