The top two are washers for the bolt on the oil filter housing feeding oil to turbo. The biggest one looks like washer that goes on oil filter housing, centre large bolt. The smallest ones look like injector nozzle seals and three and four from the top look injector collar seals.

It shouldn't need much more force then what is required when rotating without the pistons and rods. The extra resistance will be the rings, main thing it should feel consistently smooth after initial force applied. If you feel its too much you will have to bactrack. using the arp studs with higher torque value in comparison to factory spec can put your mainline out of roundness. The cylinder block would require align honing with the arp fastners to get it back concentric. Wd40 the bores and see if feels better. Good luck.
