No.

No it not healthy to keep a secret

No

Hell no

It depends on the subject matter the secret centers on. Everyone is entitled to privacy and sharing of themselves to the degree they feel comfortable doing and being vulnerable for, but if it comes down to whether I'd like secrets to be kept from me (or for me to keep them from my partner)...my preference would be to have a partner that is my confidant and for whom I could be a trustworthy keeper of secrets 😇

No. Period.

Hmm not unless it's a surprise

no es bueno guardar los secretos

sometimes

Only if the secret would really hurt them

I would say no. You shouldn't have to keep secrets from them because you should be able to keep secrets with them because you trust that it will stay between the two of you.

Nope. It is not healthy unless it is done for something good for your partner. now there's a thin line while considering what is good for your partner. your personal gains should not outweigh what is good for your partner. And you should not present the reason behind keeping secret as something you are doing for your partner and actually the motive is your self interest.

Noooooo

Absolutely not

Absolutely not, unless its about a gift for them.
