Hi,
Most dogs view their crates as their dens and so are ok with being inside. Make sure you have something for your puppy to do in the crate, a kong is good stuffed with goodies so when you leave in the morning you can give it to her or you can give her a sterlie bone (make sure its not something she can distroy or chew up into pieces). Make your puppy's crate into an enjoyable place. I have a small container of cheerios on top of my crate, each time my puppy goes in I throw a few pieces inside and say kennel, now at 7 months old she can hardly wait to get inside the crate. Being in crate for that many hours may seem like a long time to you but to a dog it doesn't really matter, most dogs sleep when not busy anyway, which is usually most of the day.
Like was said before, do not let your puppy out of the crate when she is making noise. At 5 months she can hold her potty and so you don't have to worry about that. When she is quiet for more than a minute or so then you can let her out. This goes for every time you open the door. She will quickly learn in order for the door to open she must be quiet. If she continues to bark and whine while in the crate ignore her, don't say anything to her, just let her bark. You might not get a good nights sleep for the first few nights while she figures out the new rules but in the long run it will pay off. You might try putting a towel or something to cover the door so she can't see what is going on outside the crate. Patience and consistancy are the key. Hang in there.
