I wonder if there is a problem in reporting more than one H1 tag within a page, more in relation to SEO, if Google condemns this type of action.
And also, if there is a problem of first informing an H2 tag and then an H1 tag, in that order anyway.
Does anyone know?
Yes, it is important to only use a <h1> tag because this tag indicates the main subject approached on your page, the main focus of the page in question.
The other heading tags like <h2><h3><h4><h5> are like subheadings of your page, and speaking of SEO, would be like complementary keywords .
Examples of Heading Tags:
<h1>Buffet Infantil da Carochinha</h1>
<h2>Festas temáticas</h2>
<h3>Festas do Barney</h3>
<h3>Festas dos Angry Birds</h3>
<h3>Festa da galinha pintadinha</h3>
<h2>Venha visitar a casa na Vila Olímpia - São Paulo</h2>
<h3>Ponto de referência</h3>
<h3>Estacionamento</h3>
Note that the content of heading tags starts from the most relevant <h1> to the least relevant <h3> , where <h1> is the main subject of the site, and the rest, subjects related to the main content of <h1> in question, that yes, can be repeated, because the main focus is kept, clarifying for the user, what the page mainly presents, and this topic, yes, with subtitles related to the title, which may be yes, more than one. / p>

Hierarchy issue the h1 tag has visible power [1] greater than the h2 tag, and so on. The correct usage is: h1 for title and the others to indicate subtitle.
The only problem of using them out of order is that for SEO the information contained may no longer be relevant.

No, there is no problem using more than one tag H1 . It's a good idea to not overdo it, of course, but if you need to use one or two tag's H1 there is no problem, said by a Google Eng:
Try to use a H1 for each page. Use the tag for the main title of the page, not for miscellaneous items. For this, use OL
