Answer 1

Just put the buttons inside the same form and div
<div class="second">
<div class="col-md-12 text-center">
<form>
<button class="btn btn-primary btn-lg" type="submit" formaction="1klasse.html">1.klasse </button>
<button class="btn btn-primary btn-lg" type="submit" formaction="1klasse.html">2.klasse </button>
</form>
</div>
</div>

Answer 2

Since you are using bootstrap, there are a few things you need to know:
.col class will not work without putting the class within .container and .row classes. The other important thing is that the column numeric sizes add up to 12; right now yours add to 20. So your code should look more like this:
<div class="container">
<div class="row">
<div class="col-12 col-md-6">
<form>
<button class="btn btn-primary btn-lg" type="submit" formaction="1klasse.html">1.klasse </button>
</form>
</div>
<div class="col-12 col-md-6">
<form>
<button class="btn btn-primary btn-lg" type="submit" formaction="1klasse.html">1.klasse </button>
</form>
</div>
</div>
</div>

<div class="col-md-4 text-center">

<button class="btn btn-primary btn-lg" type="submit" formaction="1klasse.html">1.klasse </button>
</form>
</div>
<div class="col-md-8 text-center">

<button class="btn btn-primary btn-lg" type="submit" formaction="1klasse.html">2.klasse </button>
</form>
</div>
</div>

Answer 4

<div class="second">
<div class="col-md-12 text-center">
<form>
<button class="btn btn-primary btn-lg" type="submit" formaction="1klasse.html">1.klasse </button>
<button class="btn btn-primary btn-lg" type="submit" formaction="1klasse.html">2.klasse </button>
</form>
</div>
</div>
The buttons were in different columns, so it went one line down.

Answer 5

Before looking into the answer below, I suggest that you read about boostrap grid system. Each row has 12 columns.
Your first <div> used up 12 columns, and that's why the second button of the second <div> is on the new row/line.
