Can our fish live together?

I am going to college and I want to take my fish with me. I have a 10 gallon tank with one guppie, two serpaes, and one small sucker fish. I told my roommate this and she told me that she has a betta. I want to know if we can put all our fish into one tank. If anyone has any answers about these specific fish breeds mixing with bettas, it would be greatly appreciated!
