Will guppies be ok with dawrf gouramis, platies, other guppies, and neon tetras

I have a 20 gallon aquarium which is cycling right now. Would it be ok to put: 3-4 guppies, 2 platies, 1-2 dwarf gouramis, 6-10 neon tetras, and 1 small algae eater? Will all of them be ok to each other, and can a 20 gallon take that many fish?

The amount of fish sounds good. I don't recommend the gouramis, just because they have a bad reputation for chasing and nipping tails. It's not always a problem - but it's a risk.

I would get an algae eater(gets 7 in big) or an octocinclid (gets 2 inches big). Please do not get a plecotomus. They get very big very fast. (those are all 3 types of algea eaters I named)

I also recommend to only get male guppies. They are much prettier! If you get females you'll have babies like crazy and soon have a crowded tank.

Some fish that would get along with the ones you mention that I recommend are:

-Glass fish (look very cool)

-Mickey Mouse Platy (Has mickey mouse on his tail!)

-African Drawf frog (Yes a frog, but he's basically just like a fish. Has to be in the water at all times and will eat fish food. Very little guy, only gets about 1-in big)

- There are lots of cory catfish. They mostly only get 3 inches big. They are bottom feeders, so they will help to eat all the food at the bottom of the tank, keeping the tank a lot cleaner. There are tons of different kids.
