[SalesForce] How to make field disabled using validation rules

I have two fields checkbox and a textbox field, if the user clicks on the checkbox checked than I want to enable the textbox field otherwise remain disabled.
I'm not sure if this is possible using validation rule and I'm working on a salesforce standard page.

It sounds like your requirement can be stated:

If Checkbox__c is checked, require TextField__c be populated. If Checkbox__c is unchecked, require TextField__c be empty.

You can validate as follows:

Checkbox__c == ISBLANK(TextField__c)

You will still need some user training on the layout itself (it won't enable/disable the input element), but the errors should be self evident to them.

[SalesForce] write a validation rule to make a field enabled or disabled based on picklist value

You can use the validation rule to make sure that the record cannot be saved unless the Days text field is filled in if the picklist value is 'other'.

AND(
    ISPICKVAL(Cycle__c, "other"),
    ISBLANK(Days__c)
)

This will give the user an error if they try to save a record where the picklist value os other and the days field is left blank.

You cannot though control whether or not the days field is enabled though. You would need a visualforce page to accomplish this functionality.

[SalesForce] How to make a field editable only if a checkbox is checked

You cannot allow them to edit this text field if you make it unallowed by removing access to profiles.

What you can do though, is allow them to edit by profile, but use a VF page in order to display this field. You can then put this VF page on the page Layout for the object. Use the VF page and/or Controller in order to control access to that variable.

<apex:page standardController="Account">
  <apex:inputField value="{!Account.MyTextVal__c}" rendered="{!Account.IsEditable__c}" />
  <apex:outputField value="{!Account.MyTextVal__c}" rendered="{!!Account.IsEditable__c}" />
</apex:page>
