How many distinct complete graphs are there with at least 5 and less than 10 nodes?

Note: a graph is considered complete if for any two nodes on the graph, there is an edge between them.

Let $K_4$ be the complete graph with 4 nodes. What is the biggest degree of any node on this graph?

Note: the degree of a node is the number of edges that connect to it.

Let $K_5$ be the complete graph with 5 nodes, how many edges does it have?

How many complete graphs with at least 1 edge and at most 50 edges are there?
