Can my stepmother evict me if the house is in my name?

for the record i'm 16, recently my stepmother evicted my dad, because she said "i felt threatened" she just wanted him out because he wants a divorce, now she wants to evict my grandma,brother (whom is 10), my uncle that pays rent, and also she doesn't pay for the house. so nothing is in her name, because of my dad eviction he sign the house in my name (she doesn't know that). so my question is, is it possible for her to evict me if so what can my dad do to prevent it and can i evict her instead? btw she is a horrible person. and i forgot she also have 3 kids for my dad.
