[Grammar] He is happy because he won a lottery

[Roktim]

"He is happy because he won a lottery."
"He is happy because he has won a lottery."
"He is happy because she'll come at the party."
"He speaks well because he is a native speaker."

I am confused about the sequence of tense. Please help me.

This is not a good post.

Try to work out exactly what you want to know. Make sure you ask only one specific question, involving only either one or two sentences.
