It is in the order you should put the answers as. This is simple because of there is more than one person in the sentence you would use the plural form of encantar:encantan, and if it is only one use the singular form:encanta
It can be either "quería" or "quiero"
It depends on what do you want to say.
If you want to say "I wanted to go to the dance" use "quería"
If tou want to say "I want to go to the dance" use "quiero"
Good luck.
