Answer 1

If you want a perfect arc you can use shape-outside to create a circle or ellipse that the text will follow.
You can see how this works
However support is spotty to say the least.
div{
shape-outside: circle(50%);
width: 140px;
height: 140px;
float: left;
}
<div></div>
<span>

</span>

Answer 2

You can achieve the same result with one class and one rule on that class. The trick is to repeat the elements inside each other:
.blubb {
margin: 5px 0 5px 10px;
}
<div class="blubb">
Lorem ipsum dolor sit amet
<div class="blubb">
Lorem ipsum dolor sit amet
<div class="blubb">
Lorem ipsum dolor sit amet
<div class="blubb">
Lorem ipsum dolor sit amet
<div class="blubb">Lorem ipsum dolor sit amet</div>
</div>
<div class="blubb">Lorem ipsum dolor sit amet</div>
</div>
<div class="blubb">Lorem ipsum dolor sit amet</div>
</div>
<div class="blubb">Lorem ipsum dolor sit amet</div>
</div>
<div class="blubb">Lorem ipsum dolor sit amet</div>

Answer 3

As Dale said, use shape-outside for a pure css solution. However due to browser support we have to find a lower-level solution.
Contains comments for non-jQuery solution, code contains jQuery.
var ps = 9;//paragraphs
var i = 1;//start id
var x = 0;//left position
var amount = 50;
for(i=1;i<ps;i++){
//calculate left position in arc
//(i/ps) gets value between 0 and 1, Math.PI is to make it radians for sine, *amount is max indent
//bearing in mind this bit can be changed to give more desired effect.
x = Math.sin(((i-1)/(ps-1))*Math.PI)*amount;
//get element using jquery and set its text-indent to x
//otherwise you could use document.getElementById('p'+i); and textIndent JS property if you dont want jQuery.
$('#p'+i).css('text-indent', x+'px');
}
