My family have 3 There are three people in my family - including my dad, my mom and me.

"My family" is singular so when you do use it, you would follow it with "has". However, my version above is more natural.

My dad is 50 years old no comma here and he is a fiber optics technicians technician (or cable technician; I'm not sure about that, which. I've just searched on Google and it call like that and both job titles are possible).

You should ask your dad what his job title is. It would be easier than trying to construct the sentence above.

He really likes broth-based dishes like pho, bun bo, v.v...

The third person singular form of regular present simple verbs always has an "s" on the end.
I have no idea what "v.v..." means.

He loves repairing electrical things like fans, light bulbs, washing machines and a lot of other things.

See my note above about the third person singular present simple.
Note my corrections to your use of the singular where it should have been plural (nouns).

My mom is 48 years old no comma here and she is a preschool teacher.

We don't connect two halves of a sentence with a comma. Study "comma splices".

She likes sweet things like smoothies and cookies.

See my notes above about third person singular verbs and singular/plural nouns.

She loves watching tv TV series.

Always capitalise "TV".

My mistake. "v.v..." in VietNam like etc in English

Say:

In Vietnamese it's comparable to "etc." in English.
