"Head hop" used to be a proper style (a few centuries ago), but not anymore.

You're fine as long as you have good reasons for switching POV and only involve one POV at a time.

Warning: There is a danger of using multiple POV in 3rd person (the point of it is greater objectivity in the narrator, which is easier to accomplish in 3rd person; POV switch is an option). Danger: it is very possible to become distracted and to enter far too many characters' heads, confusing and possibly destroying the story. Keep your focus!
