How to say these in Khmer?

this is quite a lot but i'm willing to take anything. i was just wondering how to say the pronouns in khmer? like he, she, me, i, we, us. also, i'm cambodian myself but i'm not fluent. and i just wanted to know how you say, grandma/grandpa in khmer? is it, puh-paw and gong? b/c for another grandma in my family, i call her "ma-t" and it's confusing. also, how do you say time in khmer? like 1:30 and the word time? :P also, how do you say the 10's in khmer? like 10, 20, 30, etc. also, what does "sux-suh-bye" mean? is that like how are you..? it's okay if you don't know all, anything you know is helpful!
