What made you confused? could you make it a bit more specific..

I think the angle,when i align yahsat on 90cm i lifted the dish 52 degree east but here on 180cm it didnt work like that.

52 degree east is the location of the sat(has nothing to do with the parameter values on our side).
How you set your elivation and azimut angle depends on your location.
How we see this sat from addis(ethio)has been discussed[You must be registered and logged in to see this link.].
Both dishes will have the same azimuth and skew angle as mentioned in the above link.
The elivation angle on the sacle also reads the same on the dish plate reading but
the 90 dish is an offset dish while the 180 is not.
That means the 90 will look more vertical by around 26 degree(the offset angle) than the 180.
