Assuming you'll be running regex in JavaScript, your regex will be.

/^(\/.*?\/)([^/]+)/gm

and replacement string should look like $1whatever

var str = "your url strings ..."

var replStr = 'replacement'; 

var re = /^(\/.*?\/)([^/]+)/gm;

var result = str.replace(re, '$1'+replStr);

console.log(result);

based on your input, it should print.

/category1/replacement/item
/category2/replacement/item
/category3/replacement/item
/category4/replacement/item
/category5/replacement/item

We devide it into 3 groups 1.part before replacement 2.replacement 3.part after replacement

yourString.replace(//([^/]*\/[^/]+\/)([^/]+)(\/[^/]+)/g,'$1' + replacement+ '$3');

Here is the demo: https://jsfiddle.net/9sL1qj87/
