Thank you for the replies.

The small metal can type capacitors are 0.2uF, 0.3uF, and the 3rd is unreadable so I'll assume they are non-electrolytic.

In regards to the 16uf/450vdc, I have attached a close up with one of the outside leads is obvious negative and the other outside lead connects to the negative of another capacitor so safe to assume you are correct? Any special way to connect the new cap since it will only have 1 negative lead?

I'm planning on replacing the wax paper caps and small metal caps with polyesters. One of the wax paper caps is 0.056 uF, is it okay to replace with a 0.05 polyester?

Thanks
