Да уж. . Пять ответов выше, и ни одного абсолютно верного.
1) If the weather is nice tomorrow, we will go out of town. -1 тип условных
2) If my brother had any free time now, he would HELP me. (В условных предложениях после if предпочтение отдаётся any, хотя в данном случае some тоже возможен. ) - 2 тип условных
3) If I had seen him yesterday, I would have asked him about it. - 3 тип условных
Про типы условных предложений можно почитать в Интернете.

The first conditional: I'll call you if I work late.
