Firstly, it seems that Alice is just a normal girl with no particular physical or magical abilities, so it is unlikely she could win against the other three fighters. That leaves Alice, Alice and Alice. I will assume that Alice can re-enact while fighting the feats she performed will dreaming e.g. growing indefinitely tall which is surely the most useful in combat. However, she has no particular will to fight nor combat training.
What about the remaining two contestants? Alice is a magician, a very skilful puppeteer and also somewhat of an artificer. Alice is an idealized perfect doll who appears to combine the talents of all Rozen Maidens, including their combat abilities which are certainly impressive by doll or human standards. Note though that Alice is used to danmaku fighting, helping her dodge ranged attacks from Alice.
In the end, I think it depends on the amount of preparation you allow for the fight. The giant Alice could quite easily stomp out the others. Barring this, Alice would probably win thanks to the sheer number and strength of her dolls, even though her magical powers are probably weaker than Alice's.
So, I'm going to go with Alice winning here.
