Can a group of people use Bridge to share/filter photos?

I work for a small business which installs custom closets and garage cabinets. We are seeking the best solution for organizing and tagging photos of our installations. Our goal is to enable salespeople out in the field to easily access photos that exemplify specific options the client is considering. (i.e. client is considering shoe racks in a white closet and would like to see photos).

Could Bridge (or other Adobe app) work for a group of users such as ours which would include an admin who uploads photos and enters key words, as well as 6-8 others would would frequently need to filter by key words?  In other words we would all need to have the ability to filter the same set of photos by unique sets of key words, without the admin having to "share" or "export". We need everyone to be able to do it independently as needed.

Some specific questions...

Can we share an account? (Multiple users logged in at once?)

Does Bridge work on iPhone/iPad?

Is there a better solution for us?

(DAM softwares are pricey and seem to be overkill on what we are trying to accomplish. Any cloud photo storage with tagging/filtering would work, but I'm having a hard time finding a happy medium between Google photos (no filters/tags) and DAMs.) 

Any input is greatly appreciated!
