Post photos of the rooms here, tell us what furniture is staying and what you need to buy, tell us what colors you like, and what your budget is. There are many here who will offer their help and opinions!

Look through houzz, magazines, catalogs, etc and start clipping or saving rooms that appeal to you. After awhile you will see a lot of similarities between the saved rooms and that will help you determine your style.

Look for an inspiration piece around which you can build your room...it can be fabric, art, even a plate or a blouse or a picture from houzz or a magazine. Once you have that, it helps give you a direction to go in and it will get easier to decide.

Excellent advice from both posters. You can't begin in a vacuum, and we first need to see your space and you have to have a clear picture in your head toward which style you gravitate, and which colors you love and/or hate. After that it becomes much easier to put together a look you'll be very happy with.
