let's see what else he has to say here. what does “has to” means？
what kind of tense of this sentence？And how to understand the words“has to do sth.”
Thanks for your help

Question

Answer

The tense is present simple.

Grammatically, the construction 'has ... to say" is similar to the patterns in "He has [some work] to finish" or "He has [some money] to spend" or "He has [nothing] to do".   If you have something to say about a situation, this means that you have an opinion which you want to express.

"Let's see what else he has to say here" means this:

"I'm sure that Jack has something else to say about this situation. I think we should let him say it."

Answer

Normally "have to" means that you "must" or "need" do something.
For ex., I have to go to my work (the meaning will be - I must go to work).

But in your sentence "he has to say" - means exactly what the previous girl told you - That means "he has something in his mind to say and we should ask him, what is in his mind".
