If the circles have the same radius then an infinite number, and if they do not, then none.

What are the 2 ways of common external tangent from common internal tangent?

Common external tangents and common internal tangents are two types of tangents that can be drawn between two circles. Common external tangents touch each circle at one point without intersecting the line segment joining the circles' centers, while common internal tangents intersect this line segment. The key difference lies in their geometric relationship to the circles: external tangents do not pass between the circles, whereas internal tangents do. Each type can be determined based on the relative positions and sizes of the circles involved.

When are two circles concentric?

When they have the same centre. As a consequence, the distance between the two circles, along any common radial ray, is a constant.
