The standard reduction 4x4 beginner’s method says as the second step, to pair up all the edges then. You didn’t pair all of them up, hence why a couple are unconnected
No, that's not possible. You've got the centers in the wrong spots. You need to swap red and orange.I tried it but got the same result. Is it possible in the 4x4 for one corner piece side to correspond to the right colour but the others dont? Because in the 3x3 this is impossible. Either all three sides are wrong or all are correct. In 3x3 on side right and other two swaped isnt possible for corner pieces.
You have PLL parity. Opposite PLL parity is solved by r2 U2 r2 Uw2 r2 Uw2, where r is the second layer from the right, U is just the top (Up) layer, and Uw is the top 2 layers. For adjacent parity you can either do opposite parity and then a U perm, or set up the two adjacent edges so they're opposite, and the resulting algorithm is R U R' U' r2 U2 r2 Uw2 r2 Uw2 U' R U' R'.
