Yes.

Each of these sentences is compound-complex -- meaning that there's at least one dependent clause plus two independent clauses.

The two independents make it compound.
Adding the dependent makes it compound-complex.

Um I have a question is there independent clauses in these sentences too

Of course.

Each one of those sentences has 2 independent clauses and 1 dependent clause.

Here's #1 so you can see them:

The mountain areas are barren, [independent]
but [conjunction]
the valleys are fertile [independent]
since they are irrigated daily. [dependent]

okay thank you! that makes more sense

You're welcome.
