I say Isfahan and Mashhad need mor metro line , Mashhad at least need 2 more north south line in west of the city and one east west line north of the city.
Isfahan need two north south line one in west of the city one in east and they need to continue that purple line more to east.
that's the only wat that the grid can cover all the city .
They don't. As that isn't how MRT / LRT networks are designed.
The aim is
not to cover the entirety of the built up urban area with a grid-like network. Rather, the purpose of an MRT / LRT system is to take the burden off existing high intensity traffic lanes i.e. routes where the bulk of intra-urban journeys are taking place on a daily basis, with cost effectiveness in mind. In the majority of cases, including Esfahan and Mashhad, this translates into networks which will not serve every single corner of the city.
Building - and operating - metro lines is a costly affair. In Iran each line costs around 1 billion USD to construct, while maintenance as well as operating costs are much higher than those of alternate public transit systems. Nobody will construct a line only to see metro cars remain half empty most of the time. It would amount to nothing but a waste of scarce funds.
Such would be the fate of those imagined additional lines for Mashhad and Esfahan, because people simply aren't moving in large enough quantities along those axes. Thus, for the time being these routes must be covered by ordinary buses, and then by BRT's where needed. Requirements in this regard may or may not evolve with time, depending on how these neighborhoods are going to develop in terms of population, density and places of interest they host. But for the foreseeable future, metro lines in these areas are uncalled for, seeing how they'd suffer from chronic under-usage and generate a financial burden.
When it comes to Esfahan for instance, the city map and satellite images themselves offer a glimpse into how the urban texture of western and eastern parts of town differ. Namely, anything west of Kharrazi Expressway features far lighter settlement density, presents lots of unbuilt plots and concentrates far fewer businesses, government offices and other types of amenities residents tend to commute to.

What's more, western districts are covered well by BRT as well as regular bus lines:
What Esfahan needs aren't additional metro lines in the western part of the city, but more suburban connections. Because of all urban agglomerations in Iran, Esfahan is the one with the largest suburban population relative to the population of the city proper (about 2,2 million are residing within city limits, circa 1,9 million in the suburbs). And there is significant daily transit of suburban residents to the city and back.
Which is precisely why two such links are being worked on as we speak, whilst at the same time only one inner city line is under construction. The two suburban connections in question are extensions of Line 1 to the north towards Shahin Shahr, and to the south towards Baharestan new town via the Esfahan railway station and Esfahan City Center shopping mall. Alongside Line 2, the latter suburban extension represents the most pressing priority of the Esfahan urban rail system right now.
Ultimately, Fuladshahr and Mobarake Steel Complex on the southern edge of the agglomeration, as well as Najaf Abad to the far west of it. Exactly what the master plan is calling for.
Recently i used metro and visited 3-4 metro stations in Esfahan :
For your information, that map is outdated.
Here's the currently projected inner city metro network for Esfahan:
We can see how Line 2 is going to be augmented by a bifurcation branch at Emam Hossein (a.s.) station running straight eastward, and how Line 3 is going to expand further eastward on the southern bank of Zayande Rud, then take a 90 degree turn, cross the river and traverse districts in the north-south direction, further east and more or less parallel to Line 1.
