Re: 4 women
as-salamu alaykum
we should refrain from posting our personal opinions or some knowledge which we have but we are not sure. It is best to quote people of knowledge to backup what we say so that we are not speaking from our hawa (desires).
1 - Plucking eyebrows is a sin - the text is very clear about this
2 - Removing some hair of eyebrows by cutting or trimming or shaping eyebrows - the scholars have differed some allowed in case of beautifying for her husband whereas others said it falls in the category of plucking.
3 - Removing hair from arms, legs, facial hair, between eyebrows then that is allowed.
for detailed fatawas please refer to following links:
Islam Question and Answer - Women cutting their hair and removing facial hair

And Allah knows best
