We would like to implement conditional access policies for a group of our users through Azure AD. Are these policies different from the Conditional access policies available in Intune? Also, I was wondering if there were any pitfalls to enabling modern authentication for EXOL and Skype for business?

I have not found any pitfalls to enabling modern authentication for EXO or Skype for business.
In my experience, it may take a few days before the setting will take effect for the SFB whereas there doesn't seem to be much delay for it to begin working in EXO.
One thing you may run into is your Global Admins may struggle to get remote powershell to work after enabling MFA on their accounts. To solve this, download the latest powershell modules for SFB and Exchange.

New Exchange PowerShell Module that supports MFA
The conditional access for Intune is merging into the Azure AD Premium conditional access in the Azure portal (http://portal.azure.com).
If you have a device enrolled in Intune, conditional access in Azure AD can leverage that to check compliance.

Thanks @Dean Gross. We want to use the Conditional Policies but just use password sync and not ADFS. I just wanted to triple check that turning on Modern Auth which seems to be required for the conditional policies to work was not going to hose any of my users that are still on 2013 apps.

Making decisions like this is always challenging because the requirements keep changing.
Have you seen this announcement? you can try to keep up with the changes at https://docs.microsoft.com/en-us/intune/whats-new.
Week of June 5, 2017 Microsoft Intune and Conditional Access admin consoles are generally available
We’re announcing the general availability of both the new Intune on Azure admin console and the Conditional Access admin console. Through Intune on Azure, you can now manage all Intune MAM and MDM capabilities in one consolidated admin experience, and leverage Azure AD grouping and targeting. Conditional access in Azure brings rich capabilities across Azure AD and Intune together in one unified console. And from an administrative experience, moving to the Azure platform allows you to use modern browsers

Make sure to update Azure AD Connect, there was a Security Advisory last week https://technet.microsoft.com/en-us/library/security/4033453.aspx?f=255&MSPPError=-2147217396

Since you mentioned you have users on Office 2013, you will need to roll out two registry keys as described here:
This is not required for Office 2016, as it supports modern authentication by default.
Note: If you do not roll out these registry keys, but you run the two powershell commands in your tenant for Exchange and Skype to support MFA, it does no harm. Just keep in mind the following sequence:
- enable Modern Auth (MFA) at the tenant level by running the two powershell commands (one for Skype and one for Exchange
- Roll out registry keys for Office 2013
- Enable users for MFA
So as you can see, until you enable a user for MFA, there is no impact to the users. Prior to enabling a user for MFA, just be sure to deploy the reg keys to them.

@Robert Woods Moreover ADFS and EM+S features are in the same pace. And to manage ADFS and all its proxy servers is a tough job. So EM+S is a cloud platform mainly handled by Microsoft and the best Practice is to remove ADFS as it conflicts in many places like with EM+S features as Azure AD Premium (Conditional Access policy)

Keep in mind that you control modern authentication with Conditional Access, legacy authentication like POP, IMAP, or EWS is not using modern authentication. So you might need to take care of theses workloads. For example turn them off in the services... In the past the recommendation was to use ADFS to block legacy auth:
Block apps that do not use modern authentication (ADAL)
But there is an upcoming feature to allow blocking of legacy auth with Conditional Access. It is in private preview at the time of writing and will be in public preview soon. So keep an eye on Conditional Access announcements. If available you shouldn't need ADFS anymore (except if you have other special requirements for it).

My tenants got updated today 👍 and support now Conditional Access for legacy auth:
