Wide Array of Interviews

So upcoming interviews scattered in a few different areas...
-capital markets
-ibd
-ibd public finance
- equity research

I was wondering what to say when banks ask me "where else are you interviewing?" Do I only say banks in the category I am interviewing in (Ex. for IBD @ JPM interview I would only say MS if I was also interviewing for IBD at MS, not if I was interviewing at MS for capital markets?)

Also looking for opinions on:
-does WF count as BB or MM?
-Lazard Middle Markets IBD
-TD Securities IBD?
-Barclays Equity Research
-MS Capital Markets

Any and all opinions are appreciated.
