I'm not to sure what kind of plant this is but she keeps on turning brown on her leaves. Does anybody know why this is?

It is a Dracena.
Container is Way Too Big and the soil is Too Dry. Put it into a much smaller pot, keep it evenly moist, not soggy and not dry. It will recover!
I often use this analogy. If your foot requires a size 6 shoe, your Dracena is in a size 16EEE shoe. Imagine how much pain and difficulty you would have trying to walk in shoes that big!! It is the same type of thing for your little plant.
Hope this helps. Good luck!

Thank you so much! I will try that and see if it helps.

I agree with what Bill has written and would add that a large pot does not lead to a larger plant any more than oversized shoes will make a child grow faster and bigger. Plants grow best when kept moderately potbound.

Your plant is a Dracaena 'warneckei.' I suggest removing the lower leaves that are only stubs at this point. Other leaves that develop brown tips are best trimmed with sharp scissors so as to maintain the original shape of the leaf rather than using a blunt cut. Think fingernails.

Ok how do I remove the bottom leaves? Just pull on them or clip them?

You can split the leaf lengthwise and pull the two sides of the leaf away from one another. The two leaf halves will then easily separate from the plant stem where they are attached. But there is nothing wrong with cutting. Your choice.

Ok thank you. So how do I know a right size for the plant pot? Cuz I don't wanna go to small

The smallest pot that the rootball will fit into snugly. Not unlike getting shoes that fit properly.

Ok tha n k you so much!

Why not just throw it away and get something new?

If you throw it away, you miss a wonderful opportunity to learn.

Because plants are amazing! They have feelings to just not like people.
