Normally you should use "I am learning". The alternative to "I learn", would be "I study [subject]", for example, I study geography. But you would not say "I learn geography".
English

Of the two options, only "I travel" is correct, which means that you travel often or as a hobby. For example, if someone asked you "What do you do in your time off?", you could say "I travel". However, if you are currently travelling, you would say "I am travelling."

"Families" is simply the plural of "family". This could be a family such as parents, children, grandparents, aunts, uncles and cousins (and so on). Or it could mean a group of objects that are related to each other. Although it will normally be used to refer to the first suggestion.
English

Both are correct and acceptable, although "bluer" may be more natural in most contexts. Neither are incorrect though, so you can use either at different times to add variety :)

"He swims in the pool" means he is actually swimming in the pool itself. "He swims at the pool" is using "pool" to mean the building or location where the pool is located, but not the pool itself. I'd recommend using "He swims in the pool."
English

Do you mean "although"? Although can be used in place of "however" or "but", and so can be used to introduce a contradictory argument, point, or example.

Fiesty can mean a few different things, for example someone who is determined, but it can also mean angry or aggressive.
