List-like structure: a noun not in the same category as others

Hi. Please tell me if the following are correct or not. I feel the nouns "background" in no. 1 and "family" in no. 2 are not supposed to be in the sentences, that is they are incorrect to be in the sentences. Do you think having one noun that is not in the same noun category of countable or uncountable is okay (or perhaps correct?) when it is among many in a list-like structure? I hope my question is clear. Thank you in advance.

1. ... paid the minister based on education, experience, qualification, and background.
2 ... balance your time among family, study and work.

I am sorry but could you also tell me if we could have the word "education" in plural?

... both for undergraduate and graduate educations.
