Hi,
it is better to use content types for these cases.
You will create a content type and create List based on the content types.
If you add any column in content types it will be automatically available in all the list which have this content types.
To create a site content type that people can use everywhere on a site, follow these steps:
Go to the site for which you want to create a site content type.
Select Settings  and
then select Site Settings.
Under Web Designer Galleries, choose Site content types.
The Gallery shows all the existing site content types, grouped in categories. The one that you choose becomes the parent group of your new content type.
In the Show Group box, select the group that you want to use and then choose Create.
On the New Site Content page, provide a name and description for the new content type.
In the Parent Content Type section, select the name of the parent group and then choose the Parent Content Type.
In the Group section, decide whether to put the new content type in an existing group, or to create a new group.
Click OK.
When SharePoint creates the new content type, it opens the Site Content Type page for it, where you can customize it further.
Add columns to a site content type
The columns for a content type represent metadata. To add a metadata element, add a new column.
For example, your organization might want to track specific metadata for purchase orders, such as account number, project number, and project manager. If you add columns for this information to the purchase order content type, SharePoint prompts users to provide
the information when they save their work. In addition, if you add the content type to a list or library, you can define a view to display the columns.
NOTE   
To add a column to a content type, you must first select the content type. If you are not able to select the content types that appear, the site inherits its content types from a parent site. To add a column to the content type, you must change it on the parent
site.
Go to the site for which you want to add a column to a site content type.
Select Settings  and
then select Site Settings.
Under Web Designer Galleries, choose Site content types.
Click the name of the content type to which you want to add a column.
Under Columns, click Add from existing site columns.
In the Select Columns section, under Select columns from, choose the parent group for the column.
Under Available columns, select the name of the column that you want, and then click Add
In the Update List and Site Content Types section, decide whether you want to update all content types that inherit from this site content type
by checking Yes or No.
To add a content type to a list or library, follow these steps:
If the list or library is not already open, click its name on the Quick Launch. If the name of your list or library does not appear, click View All Site Content, and then click the name of your
list or library.
For lists, click the List tab on the Ribbon. For libraries, click the Library tab.
For lists, click List Settings on the Ribbon. For libraries, click Library Settings.
Under Content Types, click Add from existing site content types.
NOTE   
If the list or library is not set up to allow multiple content types, the Content Types section does not appear on the Settings page for the list or library. To learn how to allow multiple content types, seeTurn
on support for multiple content types in a list or library.
In the Select Content Types section, in the Select Site content types from list, click the arrow
to choose the group of site content types from which you want to select.
In the Available Site Content Types list, click the name of the content type that you want, and then click Add to move the selected content type
to the Content types to add list.
To add more content types, repeat steps 5 and 6.
When you finish selecting all of the content types that you want to add, click OK.
