I had time only for the first solve 
1)R' U' F L2 D' U2 R2 B2 D L2 B2 D F' L D B2 R B L' R U F' R' U' F 
R' U //eo 2/2
B' [1] U2 F2 //222 3/5
L' F' L2 B F L' F U2 F' //G6C 9/14

[1](B R F [2 ]R' B' R F' R')  // 6/20

[2] (F R' F' L2 F R F' L2) // 7/27

Solution: R' U R F2 R' F' L2 F R F' L2 R' B' R F' R' U2 F2 L' F' L2 B F L' F U2 F' (27)


Optimal was a 26, but with a insertion that cancel 4 inside an insertion that cancel 0
