First of all please no txt speak as it puts people off reading... secondly rather than posting pics that we have to **** our heads to even read just post the actual codes...
If the post if difficult to read then you aren't going to get much of a response
The link to the Ross Tech Wiki should be your first port of call as this will have most of the information about the actual codes... interpreting what they mean of course is next...
Anyhoo... assuming you are after info for all the codes in the pics...
18010
18010/P1602/005634 - Ross-Tech Wiki
18010/P1602/005634 - Power Supply B+ Terminal 30: Voltage too Low
This happens when the battery has been removed or the ECU has been flashed... unlikely to return after clearing it
18259
Not listed is the wiki but a google produced..
18259 - Powertrain Data Bus: Missing Message from ABS Controller
Don't know about that one but google is your friend...

17978/P1570/005488 - Engine Start Blocked by Immobilizer

01262 - Solenoid Valve for Boost Pressure Control (N75): Short to Ground
Sounds like a wiring fault with the N75
16486
16486/P0102/000258 - Ross-Tech Wiki
16486/P0102/000258 - Mass Air Flow Sensor (MAF/G70): Signal too Low
Could be a symptom of the wiring issues as they share earths etc...
I would be checking the wiring first and get rid of the N75 code then look at whats left... the MAF code is normally due to airflow being below a mapped threshold for too long (there is a MAF signal too high too that is common on remapped cars)
Could be the MAF is knackered too but if the N75 is not working then you will have no boost and therefore less airflow so its most likely the reason the MAF code is there... fix the N75 issue and I suspect the MAF fault won't reappear once cleared
