You don't have to know how to last-hit with lich and crystal maiden though, same goes for most supports. They don't need the last-hits since someone else will be taking them to stack gold on one hero since items become increasingly more effective the more you have on one hero.
Other easy/noob friendly support heroes:
Tidehunter, venomancer, Ogre magi.
In DotA you usually split the 5 heroes into 5 positions.
It goes from first position to fifth position.
And it's about how much farm/gold you want on that hero.
1st position is usually a carry type hero, that ends up 'carrying' you to victory with enough gold.
2nd position are usually heroes that go mid because they need both exp and gold to be effective in the mid-game.
3rd positions are usually either going to be jungling or in the 'hard lane'.
4th positions are usually either going to be jungling or with the carry or roaming the map to attempt to get kills.
5th positions are usually with the first position protecting him in the early game.
What lanes they go to and who does what can change from game to game though, but these are very general guidelines.
lich and crystal maiden are very iconic 5th position heroes where wind-runner is great in the hard-lane and is a typical 3rd position although she has been seen utilized in the 4th position.
