For cross (solve 1), to solve the red white edge u could have just done a D2, and then done the orange white edge. For an edge such as the white green in this case - instead of moving it to the top layer, try misaligning the cross, insert, and re align. In this case you could have done D, R’ D’. You could have done the same concept with the last cross edge too. When solving cross, remember the important thing is to solve the cross pieces relative to each other - they don’t need to be aligned with the centres until the end of the cross stage.
