To remove and adjust the bottom bracket, the proiper tools are:
1. Lockring spanner (Parl HCW-5 or equivalent)
2. Adjustable cup spanner (Park HCW-11 or equivalent)
Most people don't remove the fixed cup, unless it needs replacing. If it does, you'll need a fixed cup spanner. There are multiple standards for the distance across the flats but the most common is 36mm (Park HCW-4 or equivalent)
Regarding the freewheel removal, you'll need a 2 prong freewheel removal tool designed for a Maeda/SunTour freewheel (Park FR-2) or equivalent.
The two dimples are for a pin spanner (Park SPA-2 or equivalent) that adjusts the outer cone and play of the freewheel. Most people don't touch this unless the freewheel requires servicing.
The references in parentheses are tool numbers for Park Tool Company (
https://www.parktool.com/ ) who are probably the most widely distributed tools carried by bicycle shops.
Edit: I'd appreciate the serial number and country of origin for your Focus, which may tell me the year and manufacturer. I can't quite make them out in the photos. TIA.
