how many fish can i put in 10g?

i have 2 neon tetras, 2 albino corydoras, 2 ADF's, 2 white clouds, and 2 guppies (male and female, hopefully they're fine; i'm not at home yet) in seperate 5 gallon tanks, can all of them fit in a 10g? it's the biggest thing i have now as i'm only a student in middle school and gettin money and buggin my mom enough to take me out is hard as it is. can all of those fish and amphibians stay in a 10 gallon? i used to have 5 common goldfish and a blue oranda and they were fine in there until they reached 3 in. each (oranda died somehow, was getting food ok with no difficulty) but most are in my outdoor pond. thx in advance for any answers!
