9. "We met in School time and since then kept together" - clumsy and arguably incorrect. If the two people stayed in the same house, then they kept together but not if they simply kept in touch. "We met at school and kept in touch ever since." 'School' should be in lower case.
10. "we can have animals" - if the intention is to say "we can keep pets (in our flat)" then it is ambiguous because it includes animals that are not pets and casual animals such as one-off intruders. And what about lions and tigers? Are they allowed?
13. "The first time it was horror" - ambiguous. What was a horror? The occasion of giving birth or the child itself? Maybe they mean the first few weeks. If it is about giving birth, I would say something like, "the first time was horrible."
Would only make sense if it says something like I would like to prefer coffee but unfortunately I prefer tea... which is a really awkward way of phrasing it. More likely they looked it up in a dictionary, found to like/to prefer and instead of choosing decided to use both.
