Hi Kushal Mishra,

If you want to implement it in VF Page,
Here is the sample code for your scenario, Create a VF page for below code and try to change Opportunity stage values to Prospecting, Closed Won and Closed Lost .
  
<apex:page standardController="Opportunity">
<apex:form id="form1">
<apex:pageBlock id="block1">
<apex:outputPanel >
<apex:pageBlockSection id="section1">
<apex:inputField value="{!Opportunity.StageName}" id="populate" >
<apex:actionSupport event="onchange" reRender="section2"/>
</apex:inputField>
</apex:pageBlockSection>

<apex:pageblockSection id="section2" >
<apex:inputField value="{!Opportunity.NextStep}" rendered="{!IF(Opportunity.StageName == 'Closed Won',true,false)}" id="textpop" />
<apex:inputField value="{!Opportunity.Amount}" rendered="{!IF(Opportunity.StageName == 'Prospecting',true,false)}" id="textpop2" />
<apex:inputField value="{!Opportunity.Type}" rendered="{!IF(Opportunity.StageName == 'Closed Lost',true,false)}" id="textpop4" />

</apex:pageblockSection>
</apex:outputPanel>
</apex:pageBlock>
</apex:form>
</apex:page>
Best Regards,
Mithun.

Hi Kushal Mishra,

Ok, Assume that below are the your custom object details.

1. Custom object API name is "TestObj__C".
2. Custom Picklist field API name is "TestPicklict__C" and picklist values are (Opt1, Opt2 and Opt3).
3. Custom Text field API name is "Textfield11__C".
4. Custom Text field API name is "Textfield22__C".
5. Custom Text field API name is "Textfield33__C".

Now, we have one custom object (TestObj__C) and four custom fields (TestPicklict__C, Textfield11__C, Textfield22__C and Textfield33__C).

Here is updated code for above custom object.
  
<apex:page standardController="TestObj__C">
<apex:form id="form1">
<apex:pageBlock id="block1">
<apex:outputPanel >
<apex:pageBlockSection id="section1">
<apex:inputField value="{!TestObj__C.TestPicklict__C}" id="populate" >
<apex:actionSupport event="onchange" reRender="section2"/>
</apex:inputField>
</apex:pageBlockSection>

<apex:pageblockSection id="section2" >
<apex:inputField value="{!TestObj__C.Textfield11__C}" rendered="{!IF(TestObj__C.TestPicklict__C == 'Opt1',true,false)}" id="textpop" />
<apex:inputField value="{!TestObj__C.Textfield22__C}" rendered="{!IF(TestObj__C.TestPicklict__C == 'Opt2',true,false)}" id="textpop2" />
<apex:inputField value="{!TestObj__C.Textfield33__C}" rendered="{!IF(TestObj__C.TestPicklict__C == 'Opt3',true,false)}" id="textpop4" />

</apex:pageblockSection>
</apex:outputPanel>
</apex:pageBlock>
</apex:form>
</apex:page>
Best Regards,
Mithun.
