It is always easier to answer this sort of question when the whole sentence is given - context often makes a big difference. However, 1) Bad looks is what she has is most definitely incorrect. ' She doesn't look good' is better grammatically, but may I suggest, young man, that you do not say this within the hearing of the woman you are describing?!
2)I wouldn't use any of these for your example of describing a day. It is probably common usage among younger people, but it isn't really good grammar. It would be more correct (grammatically) to say 'it is a good kind of day'. However that sounds stilted in conversation. If you just want to comment to someone that it is a good day, then "its a good day' will do.
3) Come out of it is probably the better choice. You can 'come out of' a bad experience, a bad mood, a difficult period in your life. Again, without the context of a full sentence, it is hard to be definite. Hope that helps.
