If this home and these lands belong to your parents, how could it be registered in the name of a 3rd person?
In any case, parents property is to be inherited by all children equally. Thus, this property is to devolve on all the 5 children and hence, one or more of them cannot exclude the other from inheriting the property.
You can claim your share by way of filing a court case, but this case can be filed only after the demise of your parents.
