Just curious, do you still have trouble with Norman?
Spinda: It knows Teeter Dance, so watch out for that. Get something fast to OHKO or 2HKO it.
Linoone and Vigoroth: There's not much to worry about in my opinion.
Slaking: This thing is quite a pest. It knows Counter, so watch out. You don't want to stall because Slaking has Focus Punch. Try putting a status condition on this thing, preferably sleep condition. Make sure you stay patient and save before you battle. This thing can possibly wipe out your whole team and it might take many tries.
