Answer 1

you simply need to use the get variable
create the link that will be clicked like this
the link that will be clicked on home page or any other page
<?php
$username='test';//the variable containing the username
echo'<a href="mysite.com/profile.php?user='.$username.'">
The link redirecting to profile page
</a>';
?>
the address bar will turn something like this www.mysite.com/profile.php?user=test
then on the profile page
<?php
$username_selector=$_GET['user']//in this case the value got from the link clicked is test
//then just select the necessary data using the variable storing the value got from th link clicked
?>

Answer 2

All you need to do is echo some html:
$username = "foo";
echo "profile link";
Note: I use \" to escape the "
