If I login my new Apple ID on old Iphone, will all my apps disappear?

I have always been using my husband's Apple ID on my Iphone to download apps. Recently I've opened my own Apple ID. But if I sign out my husband's Apple ID on my Iphone and sign in with my own Apple ID, will all the apps on my Iphone disappear? Or will they all stay on my Iphone? Do I have to repurchase those apps (eg. Whatsapp?) Thanks!
Added (1). Great, but when say one of my old app that's been installed with my husband's Apple ID needs an update, can I use my new Apple ID to update it or does it have to be the same as the one used when installed (namely my husband's Apple ID)?
