Your best way to achieve what you desire would be to make use of a more complex data structure such as an array or a hash. The other option of modifying the scalar variable name itself (symbolic references), while it can certainly be done, is not the best way to implement such a solution - To find out why symbolic references are bad, have a read through the links referenced in this node.

For example using an array:

my @name_menu;
for (0..$elements) {
    splice(
        @name_menu,
        $_,
        0,
        qq{
<select size="1" name="M$_">
$fname
<option>GUEST</option>
<option selected>Select a member</option>
</select>
}
    )
}

Each element within the array could subsequently be called as $name_menu[0], $name_menu[1], etc. Alternatively, if you were to use a hash data structure, which would result in faster look ups, you might use code similar to the following:

my %name_menu;
for (0..$elements) {
    $name_menu{$_} = qq{
<select size="1" name="M$_">
$fname
<option>GUEST</option>
<option selected>Select a member</option>
</select>
};
}

Each element within the hash could subsequently be called as $name_menu{0}, $name_menu{1}, etc.

Good luck.
