) ответ да. Прямые параллельны, если они лежат на одной плоскости, перпендикулярной двум первым плоскостям.
 красные прямые лежат в параллельных плоскостях и при этом параллельны в третьей плоскости
б) ответ нет. Признак скрещивающихся прямых.
Если одна из двух прямых лежит в некоторой плоскости, а другая прямая пересекает эту плоскость в точке, не лежащей на первой прямой, то эти прямые скрещивающиеся.
Т. е. если прямая по условию находится в параллельной плоскости, она не как не может эту плоскость пересекать
