Is this a skin cancer if red raised smooth?

Hard to know. It could be, but there is no way to know in this forum. If it is enlarging with time, ulcerating, bleeding, etc that would be more concerning. Either way, get it checked out by your pcp or dermatologist.
Need examination. It's impossible to diagnose skin cancer without examination. Skin cancer can present as various forms even if it's flat and red. There are different types of cancer such as squamous cell, basal cell, melanoma and rarely skin appendages cancer. You need to have you doctor examine you to be sure.
Skin lesion. It's not possible to give you an answer with 100% certainty. Basal cell carcinoma can appear as you describe. However, there are several skin lesions that can look like what you describe. Having the lesion examined by a dermatologist would be your best option.

I wear sunscreen outdoors, but I have a raised mole. Do I have skin cancer? Is SPF 50 sunscreen going to protect me more than SPF 15?

ABCDEs of Melanoma. I recommend going to see a dermatologist since I am not there to actually see it. The abcdes of melanoma are:a=asymmetry(one half unlike the other half), b=border (irregular, scalloped, poorly defined border), c=color (varied from one are to another), d=diameter (while melanomas are usually greater than 6mm they can be smaller when diagnosed), e=evolving(change in size, shape, color).See a dermatologist.

I have a raised brown flat bump on my right hand its small like a centimeter big and I just want to know if its skin cancer or not.

Probably not. At age 20 it is statistically very unlikely to be cancer. A mole is brown but 1 cm diameter,is a bit large so it is best to have a doctor check it. You may just be reassured or have it removed either for diagnostic or cosmetic reason.It would be guesswork to give an accurate diagnosis online.Take care. Read more...
See your derm. Any new or changing skin lesion should be brought to the attention of your dermatologist. If they are suspicious of the lesion, a simple skin biopsy is performed to obtain a diagnosis. And also remember to limit your exposure to UV radiation. Wear sunscreen with an SPF of at least 30 and try to cover up as much as possible. Read more...
