This is covered here.
You can have as many IDP as you want.
The first step of the user journey will then have as many ClaimsProviderSelections as you require. This example is for adding Azure AD.
<ClaimsProviderSelections>
...
<ClaimsProviderSelection TargetClaimsExchangeId="AzureADContosoExchange" />
</ClaimsProviderSelections>
Update
Also, look in the B2C starter pack.
<UserJourney Id="SignUpOrSignIn">
<OrchestrationSteps>
<OrchestrationStep Order="1" Type="CombinedSignInAndSignUp" ContentDefinitionReferenceId="api.signuporsignin">
<ClaimsProviderSelections>
<ClaimsProviderSelection TargetClaimsExchangeId="FacebookExchange" />
<ClaimsProviderSelection ValidationClaimsExchangeId="LocalAccountSigninEmailExchange" />
</ClaimsProviderSelections>
<ClaimsExchanges>
<ClaimsExchange Id="LocalAccountSigninEmailExchange" TechnicalProfileReferenceId="SelfAsserted-LocalAccountSignin-Email" />
</ClaimsExchanges>
</OrchestrationStep>
<!-- Check if the user has selected to sign in using one of the social providers -->
<OrchestrationStep Order="2" Type="ClaimsExchange">
<Preconditions>
<Precondition Type="ClaimsExist" ExecuteActionsIf="true">
<Value>objectId</Value>
<Action>SkipThisOrchestrationStep</Action>
</Precondition>
</Preconditions>
<ClaimsExchanges>
<ClaimsExchange Id="FacebookExchange" TechnicalProfileReferenceId="Facebook-OAUTH" />
<ClaimsExchange Id="SignUpWithLogonEmailExchange" TechnicalProfileReferenceId="LocalAccountSignUpWithLogonEmail" />
</ClaimsExchanges>
</OrchestrationStep>
You'll see there are two "ClaimsProviderSelection", one for local accounts and one for Facebook.
