So you are using iBuddy and trying to make it look exactly like the link?
If that is the case than follow these steps:

Home page:
Pages -> add new page and assign to the template “Home”.
Settings -> Reading and set the Home page as static page and chose the previously created page.

Home page widgets:
Appearance -> Widgets and add the widgets that you want to show on home page under the “Home Sidebar”.

Home page settings:
Appearance -> Them options -> Home page
Here you will find all the settings related to the Home page. The default options are already fine.

I’m not sure I understand your question, could you be more specific.

Follow this steps to deactivate your plugins:

Try to disable all the plugins you have and re-update your WordPress

There are few plugins that gives you the possibility to have the backend in different language than the frontend. Here is one that I usually use:

This isn’t your design. You are using a premium theme.

Go to: Settings -> Permalink and hit Save Changes

To check for subpages you can use: https://codex.www.ads-software.com/Conditional_Tags#Testing_for_sub-Pages

Than from there you can build your check and output either the subpage title or the parent page title or both both titles.

Did you try to check here: https://www.ads-software.com/plugins/search.php?q=ads?

The h2 you are targeting is taking the color from a specific class which is .entry-content h2 so to apply your CSS you have to target the same class for example:

.entry-content h2 {
        font-size:large;
	color:#990000;
	font-weight:900;
	font-family:Verdana;
}

If I understood what you are asking then the answer is no you don’t need a plugin to do that… WordPress allows you to create/use custom menus.

I’m sorry but as @wpyogi mentioned above, the support here is for themes provided from:
https://www.ads-software.com/themes/

The developer of touchfolio does not seem to be providing support for the theme so what I can tell you is that make sure you are following the instructions for creating a child theme correctly and than search for the template that is used for the blog and copy that over to your child theme.

Codex page explaining child themes:
https://codex.www.ads-software.com/Child_Themes
This will help you understand more about how child themes works and how to create your own.

Codex page explaining the template hierarchy:
https://codex.www.ads-software.com/Template_Hierarchy
The other page link explains the template hierarchy so you can read that to get to know more about how WordPress uses templates and try to find which template your theme is using to show the blog section.

@rahul0010, Check out the FAQ of the plugin here:https://www.ads-software.com/plugins/tabbed-login/faq/
If you don’t find what you are looking for than follow what @wpyogi suggested you and ask in the plugin sub-forum.

What you are trying to do requires customization… However, I would suggest you first to start creating a child theme so you can have a safe place to apply your customizations.

By saying safe I mean that your customization will not be delete it if you ever update the parent theme.

It looks like transparent for me…
