There are no problems about it. remember that you have to have at least 20 gallon tank, because your gourami and shrimp will need to have space.

as long as the tank is big enough and there is enough visual barriers in the tank, it would be fine to keep thoughs species together.
Only fish in the same class gourami, and try to keep the fish around the same size as the fish you have.
It is generally recommended to keep 1 ghost shrimp per gallon in a freshwater aquarium. Overcrowding can lead to stress and aggression among the shrimp.
ghost shrimp,
Ghost shrimp are small, transparent freshwater crustaceans that are often kept as aquarium pets. They are typically used to help keep the tank clean as they feed on debris and algae. Ghost shrimp are known for their see-through bodies, which can make them hard to spot in the aquarium.
It is recommended to keep at least 3-5 ghost shrimp together in an aquarium to promote social interaction and reduce stress.
If your ghost fish keeps jumping out of thee tank, it might be because it is in a tank with territorial fish that does not want it in the tank and keep forcing it out. It does not feel comfortable there so it jumps out.
Keep them in the refrigerator but not in water, just in a sealed container.
That should be fine, but keep an eye on how the angels behave towards the gourami once they get bigger as they may bully it once they are full grown.
That's a very nice setup! :) corydoras and most tetras keep to themselves and i personally think a gourami would be a great centerpiece in a tank. But corys live in schools, so you should buy at least five. And since corys breed a lot, you should buy every few specimens from different stores.
No, but some tank mates you can consider if your betta is in a 10 gallon tank are neon tetras, rasboras, white cloud minnows, or even some ghost shrimp.
The guppies may well rip the legs off the shrimp.
