put three puppies and a cat in a travel kennel only big enough for one full grown dog same breed as the puppies??
Not to be rude, but that's a bad comparison. Fish should not be compared to humans or other pets. Instead, an explanation as to why Techguy41 needs to reconsider his stock would be more appropriate.

ok, please help me then, what are ALL the types of freshwater fish
Tech, there are many many species of fish which can be grouped in a number of ways. Some people consider tropical fish to be freshwater and saltwater fish, which come from warm water areas. In your case however, we're talking about freshwater tropicals.
Before you consider buying more fish, take your setup and it's current inhabitants, into consideration.
From your post, I gather that you have a 10g tank, with 4 guppies and 1 or more goldfish.
The thing about goldfish, is that they get large. Even those little feeder goldfish get big. Most people don't realize how large they can get, or they believe that they "only get as big as the tank they live in." That's not true. What happens, is that the goldfish have no room to grow which leads to a very premature death. So because of their large size, goldfish should be kept in at least a 55g tank. Some people flat out don't care, and they have no problem with keeping large fish in aquariums that are too small for them. That's not responsible or respectable fish keeping. The serious aquarist, researches the needs and limits of the fish they plan to keep, and setup their tank accordingly.
As far as goldfish in warm water, that's really not a big deal. Goldfish ponds here in california get 80F+ in the summer. I have a goldfish in one of my tropical community tanks, and it's growing rapidly and is very healthy. The only issue with having goldfish in warm water is that they breathe faster, which means they need more oxygen. That issue is easily solved by making sure your filter causes surface agitation, or you use an air pump with an air stone or some sort.
The point being, your 10g is too small to house goldfish of any kind. If you care about your fish, and wish to keep them, you should buy a larger tank around 55g. Your goldfish will fill it up in no time.
Now for the guppies.
Guppies are well known for reproducing in large numbers. A lot of aquarist breed them as feeders for their predatory fish. If you plan on keeping a community with your guppies, you should plan on having a few fish that will eat the babies of the guppies. That sounds cruel, but if left alone, the guppies will overcrowd themselves to death.
If you don't want to worry about guppies breeding too much, then just keep males. If you do that, that opens your options for other fish.
The best thing to do is browse the fish profiles on this website and find out what you like. Most fish profiles on the internet will give you information on how to care for that particular fish, i.e. tank size, ph, temp, temperment, etc....
Even browsing the threads in this forum can yield a surprising ammount of info, just by reading what others are discussing.
Good luck with your research, and don't be afraid to ask questions.
