Just a few questions...

The seller selling the 2.5 x 1.5 x 1.5ft tank started selling 30 gallon tank instead. So I scrolled some more and found a 50 gal. Planting it and stocking with 15 Cardinal Tetras, 10 guppies, and 6 Black Neon Tetras. Is it enough space for them to live together comfortably?

You should probably not put guppies with tetras as they need opposite water parameters. For the 50 gallon you can add more fish than just a few tetras. For one, you could add other types of fish like cory catfish, plecos, snails and shrimp, as well as more types of tetras. You can also have congo tetras, which will be able to live in your tank size, provided there are enough plants and the water parameters are correct.

Could we have a picture of the tank please?

Haven't got the tank yet due to this annoying EMCO, but will be picking it up if I can.

50G isn't quite large enough for congos, 75G minimum needed....
 
The dimensions are generally more important than the volume, as these (length and width) have to be considerate of the fishes' swimming needs. A 4-foot (120 cm) long tank is minimum for Congo Tetras which need to have a group (10+ is best) and the males will frequently hold what I term "relay races" with two of them racing down the tank. They won't be able to exercise this inherent interactive behaviour in shorter tanks.
 
In that case, I think I can add 10 Cardinals(20 gallons tank space), 6 Black Neon Tetras(15 gallons tank space), 1 male betta(is it ok to have the betta in the community tank?) 10 Ember Tetras(10g tank space), and a few red cherry shrimps. Sounds good?

Betta‘s in community tanks is always a contentious discussion. In my opinion, no, they are best kept alone.

Except for the betta, fine. Bettas are not community fish, and should never be placed in that situation. I have outlined the scientific reason in several threads. Make sure you have floating plants in the tanks with tetras as these are primarily forest fish that live in very low light environments and some (cardinal tetra) even have what one author called a light phobia.
 
I see. The rule of thumb is 1 inch per gallon. Cardinals are about 1.25 inches, but they need 2 gallons each. Not sure if this is the minimum. Is what I found correct?
 
It doesn't work like that I'm afraid.

The one inch per gallon rule (which is not a good rule) refers to the tank not fish.

A tank of x gallons can hold x inches of fish. This is the most fish a tank can hold (and the rule only applies with fish which never grow more than 3 inches long). So the rule says a 10 gallon tank can have 10 inches of fish; a 100 gallon tank can have 100 inches of fish.

You cannot say a fish x inches long needs x gallons because all fish have a minimum tank size to allow them to swim properly.
For example, cardinal tetras need a tank with a footprint of at least 24 x 12 inches. That 24 x 12 inch footprint is the smallest they should be kept in with bigger being better.
Zebra danios are about the same size as cardinal tetras but they need a tank at least 36 x 12 inches. The reason they need a longer tank is because danios are very fast swimming fish so they need a longer tank to be able to swim properly.

A 24 x 12 x 12 inch tank is big enough for cardinal tetras. That's a 15 gallon tank so it can hold 15 inches of fish. Cardinal tetras grow up to 1.5 inches. So that 15 gallon tank could hold 10 cardinal tetras, and it would then be fully stocked.

The https://aqadvisor.com/ website gives a reasonably good stocking level once you’ve added your tank size.

You could always try that and then ask here about stuff they don’t always have such as compatibility/water types…

+1 to AqAdvisor, it isn't perfect, but a very good starting point....forget the "inch per gallon" stuff....
