I have three H1 block element in my header

Short question - is this SEO-friendly?

[tomda]

The three first elements of my header are tagged by H1.
Then I have one H2 and one H3.

I'd like to know if this is SEO-friendly?
Or should I change and go deeper, that is up to H5.

Thank you

There should only be one <h1> on a given page.
Any subheading below the <h1> is <h2>.
Any subcategory below an <h2> is <h3>.

And so on.
