Disclaimer: Everyone and every injury is different. I'm not a doctor, but someone who broke the fibula and tibia 6 weeks ago and it's dealing with similar stuff. So take it as you will.
'Usually' you'd do passive ankle range of motion exercises since about week 3/4. When you can move the ankle throughout its normal range or close to it, start working in moving it without assistance. Once you can do that you start introducing resistance exercises with a teraband or similar.
After the bone is declared 'healed', normally between weeks 4 and 6, you start weight bearing on it gradually. It's advisable to start with the foot in a scale to have a gauge. Normal to start loading it with 10/15kgs and move from there depending how it feels by using only one crutch or a cane if you like to be stylish.
Most importantly, get a physio (a proper one, not just some person who can do a sport massage) and don't ask for advice online. Those are the guys who actually study for this, have the experience, and will be able to see your case and tell you exactly what and how much.
Good luck
