Which smartphone should i go for between these:: lenovo k3 note asus zenfone 2 laser huawei honor 4x?

Well first Asus Zenfone 2 Laser has 2 model 1: with 3gb ram and 3gb ram so which one are you looking for. Well it seems you are looking for a mobile with a price range of 10,000 or below. Well my personal opinion is that don't go for huawei Honor 4X as it only provides you 8gb internal, because sooner or later you will complain about the storage. So I think Huawei is not a good option.
Lenovo K3 Note is not sleek and attractive, but its very good option for you in this list. As we can compare with other device Lenovo is the leader. I would go with Lenovo.
Lenovo K3 Note is a good option among the three.
