1 logo is fine. Additional photos belong in a portfolio and not a resume. (Exception is that in some countries like Japan, candidates are expected to attach a headshot).

I do not recommend "skill bars" on a resume. This is because it is very arbitrary and not factful. For example, if you are a 10/10 in excel, does this mean you can program and recreate excel? Can you do everything in excel? If you can do VBA but can't do linear regression, is that a 5/10 or 8/10? It's overall not a good way to assess candidates. I would rather have something more concise and concrete such as hard skills.

Yes, most hiring managers prefer traditional resume formats. Some design is okay, but try to keep it easy to read, single-column (easy for ATS to parse), and sufficient margin space (managers like to write in the columns). You also cannot predict who is the hiring manager, who may be a non-designer. This would be the safest bet.
