I am new to .net C#. I am learning about interfaces.

Note: Nested interfaces and classes can have all access modifiers. Note: We cannot declare class/interface with private or protected access modifiers. For example, the following program fails in the compilation.
Interface member declarations may include any access modifier. This is most useful for static methods to provide common implementations needed by all implementors of a class. Enumeration members are always public , and no access modifiers can be applied. Delegates behave like classes and structs.
If no access modifier is given, the method is implicitly public . It is permitted, but discouraged as a matter of style, to redundantly specify the public modifier for a method declaration in an interface.
Access Modifiers in Java are used to define the accessibility of methods and data members. There are four main types of Access Modifiers – Default, Private, Protected, and Public.
Since C# 8.0 you can have access modifier inside the interface. See this post C# 8 Interfaces: Public, Private, and Protected Members
Before C# 8.0
You should see:
Access Modifier - MSDN
Interfaces declared directly within a namespace can be declared as public or internal and, just like classes and structs, interfaces default to internal access. Interface members are always public because the purpose of an interface is to enable other types to access a class or struct. No access modifiers can be applied to interface members.
(For your questions)
Can we use Access Modifier with Interface
Yes, they can be declared as public or internal
By default Are inteface internal
Yes.
what about Access Modfiers with Inteface members.
They are public. No access modifiers can be applied to interface members.
