Queen Allenal of Ruadach’s first ability counts itself, so its power and toughness will always be at least 1/1.

The additional Soldier token won’t have any abilities the other tokens were created with. Anything else specified in the effect creating the tokens (such as tapped, attacking, “That token gains haste,” or “Exile that token at end of combat”) applies to both the original tokens and the Soldier.

If an effect changes under whose control a token would be created, that effect applies before Queen Allenal’s effect applies. If an effect changes under whose control a token would enter the battlefield, that effect applies after Queen Allenal’s effect is able to be applied.
