How to apply business rules with out breaking to patch missing data

Question

Hello Experts,
I am very new to SQL And i have no idea how to apply below  rules
Data is polling for every 5 minutes so 12 time intervals per hour 6:00  -->1
6:05---->2
6:50---->11
6:55---->12
                  6:50---->11
Missing value
Patching
Rule
No values missing
No patching
0
Time interval 1 is null
Time interval 1 is patched with the value from time interval number 2 subject to this not being null.
1.1
Time interval 12 is null
Time interval 12 is patched as the value of time interval 11 subject to this not being null.
1.2
Time intervals 1 and 2 are null
Time interval 1 and 2 are both patched with the value of time interval 3 subject to this not being null
1.3
Two consecutive time intervals (excluding both 1 & 2 or both 11&12) are null e.g. time interval 3 and 4 are null
Average the preceding and succeeding time intervals of the missing 2 values. If time intervals 3 and 4 are null then these become the average of time intervals 2 and 5.
1.4
Time intervals 11 and 12 are missing
Time interval 11 and 12 are both patched with the value of time interval 10 subject to this not being null
1.5
Some time intervals between 2 and 11 are null with 6 or more non null time intervals
Time interval is patched with the average of interval – 1 and interval + 1 subject to these not being null.
For example if time interval 5 was null this would be patched with an average of time interval 4 and time interval 6
n.b this rule can happen up to a maximum of 5 times.
1.6
Three consecutive time intervals are missing
Set all time intervals for the period as null
2.1
More than 6 time intervals are null
Set all time intervals for the period as null
2.2
This will be more info table structure
 CREATE TABLE DATA_MIN
  DAYASNUMBER    INTEGER,
  TIMEID         INTEGER,
  COSIT          INTEGER,
  LANEDIRECTION  INTEGER,
  VOLUME         INTEGER,
  AVGSPEED       INTEGER,
  PMLHGV         INTEGER,
  CLASS1VOLUME   INTEGER,

output something like FOR above sample data

Any help and suggestions to extend the code to achieve would be greatly appreciate.
Note:Here the key value is Volume to be patched for missed time intervals
Thanks in advance

Answer 1

row_number() OVER (PARTITION BY LANEDIRECTION ORDER BY TIMEID) AS RN,DAYASNUMBER,(*to_date*(timeid,'yyyymmdd hh24miss')) as cte, COSIT,
Are you in the right place? to_date is an Oracle function, and this forum is for Microsoft SQL Server which is a different product.
