A convex lens is thicker in the center than at the edges. A convex lens is like a concave mirror.A concave lens is thinner in the center than at the edges.
A spoon that you have put some food into is a concave shape. It is a cavity. A concave lens is such that it is thicker at the edges than in the middle. Convex is the bottom of the spoon. A convex lens is thicker in the centre than around the edges.
Your are mixing properties. Converging lens is always thicker in the centre and thinner at the edges. The other cathegory is the geometry of shape of the surfaces of the lens. Convex means that the shape is similar to the outer surbace of a sphere, concave means that the shape is similar to the iner surface of a sphere (or: convex = lower side of a spoon as we use it for sampling a soup; concave: upper (inner) shape of the spoon). A double convex lens is always a converging lens. A plano-concave lens is always a diverging (not converging) lens. A convexo-concave lens is the most usual shape of a lense used in spectacles. It can be either converging or diverging, depending on the radii of the surfaces.
The convex lens bulges out at the center, while the concave lens bulges in at the center. The convex lens magnifies, while the concave lens reduces.

A converging lens is also known as a magnifying lens. The shape of the lens is a double convex shape.
Concave is thinner in the center than the edges and convex lens is thicker in the center than on the edges :)

A convex lens magnifies.
A convex lens acts as concave lens when it is kept in a medium whose optical density is higher than the lens itself. And the vice-verse is also true .i.e, a concave lens can act as convex lens too .
