Cross-Bedding is a feature that occurs at various scales, and is observed in conglomerates and sandstones. It reflects the transport of gravel and sand by currents that flow over the sediment surface (e.g. in a river channel). sand in river channels or coastal environments
In planer bedding Surfaces are without cross lines, but cross-bedding is inclined.

Surfaces between layers of sediments (bedding planes) are usually deposited in horizontal sheets, but cross-bedding is inclined. Graded beds are horizontal and are usually sorted from coarse at the bottom to fine at the top.

Absolutely: there are many possibilities. The only issue is that as the cross-bedding is often not on a massive scale, this may cause graded bedding to become unnoticeable. It is clearer in a rock with only graded bedding. As the beds are often quite shallow, grading is often unnoticeable, yet it still may exist on a slight scale.
A common variety of cross bedding. Generally at a relatively low angle it resembles scooped grooves. It is formed by sand dune migration (large or small scale)

Graded Bedding means that the grain size within a bed decreases upwards.
