Meat & Milk

These chocolates have milk listed in the ingredients. Must one wait after eating meat to have them?

Hello Rabbi- is collagen powder considered meat for purposes of waiting 6 hours till having  dairy? thank you.

Does one need seperate glass keilim for milk and meat? E.g. glass “Tupperware” (not really tupperwear, but I don’t know how better to describe) containers in which food may be reheated in the microwave

can I use melamine dishes for both milk and meat?

Must I have separate dishwashers for meat and dairy?
