You can lube up the rear bolts that go into the torsion bars, they can be a nightmare to get out. The drivers side though you will have to move the anti roll bar cover out the way by undoing a 13mm bolt i think, one each side and lifting the cover and getting to the bolt that way.
Other 3 are pretty easy to see though, they are torx head bolts, cant remember if there t30 or t40 now lol. Done so many too.
Just keep lubing them up with a maintanence spray or even pour coke onto them to try and release them abit.
Ive lowered a 97-98 plate saxo and was alot easier than my 03 plate saxo so tbh they could be either seized solid or pretty easy to get out.
Providing thewy use decent titanium torx bits they should be able to get them out anyway.
Hardest part really is moving the torsion bars cus they can really be seized.
