Third from left looks like it has a cush drive, so I'll say SL125/XL175 or similar.
Mini wheel is probably late 80s/early 90s KX80. Maybe mid 90s RM80.
Second from left looks like XL175.
I agree that the far right is late drum brake RM.
The other two, NFI. TS185/250ER, maybe DR250 or KL250 at a wild guess.
