My daily routine

Let me tell (you) a little bit more about my routine.

I usually get up at about  (get up around) 6:30 am, have breakfast and go to work.
I work as a PCP and PCM departments assistant.
At about 12:00 o' clock I have lunch.
01:00 pm I go back to work and I'm still there until at 5:00 pm.
Then, I go home and stay with my family.

'still' and 'until' do not fit together.

Either:
I'm there until 5pm.
Or:
I am still there at 5pm.

Your times look a little formal - like a timetable... I would just use the following:

I usually get up at about 6:30, have breakfast and go to work.
I work as a PCP and PCM departments assistant.
At about midday I have lunch. 
I go back to work at 1pm and I'm still there at 5pm.
Then, I go home and stay with my family.

When speaking I would say the following.

I usually get up around half past six, have breakfast and go to work.
I work as a PCP and PCM departments assistant. 
Around midday I have lunch. 
I go back to work at one and work through until five.
Then, I go home and stay with my family.
