Can I use Seblod to enable the front-end users to input their details, which include their locations? Further, I would like the front-end users also to be able to search via google maps other user's locations as well.
Welcome to the SEBLOD forums! You can easily edit the user form to include their address, latitude and longitude. Using the Address to Coordinates plugin will convert the address to the correct geo location in which you can then display on the map using the Map template.
