Are spivak and apostol calculus book good even from a physics point of view for learning calculus?
I have a basic understanding of calculus but want to learn in depth more physics and for this I require more calculus
You can try out Introduction to Calculus and Analysis by Courant. The first volume deals with single variable calculus and the second volume deals with multiple variable calculus.
Depends on what your position is now. But, for anyone starting to read calculus, I would recommend Silivanus P. Thompson's amazing book, Calculus Made Easy

Its available freely, and is a masterpiece. However, for a much more advanced or rigorous footing, I would recommend Spivak over Apostol. I have read Apostol myself. Its good but not as good as Spivak.
