What is "p"?

You use RadioButtonFor to bind to your model, so your view's model will be a class that has a Lang_id field and you bind to it like

@Html.RadioButtonFor(model => model.Lang_id, "1", Model.Lang_id == '1' ? new { @Checked = "checked" } : null) English
@Html.RadioButtonFor(model => model.Lang_id, "2", Model.Lang_id == '2' ? new { @Checked = "checked" } : null) Hindi
@Html.RadioButtonFor(model => model.Lang_id, "3", Model.Lang_id == '3' ? new { @Checked = "checked" } : null)

The action will then be

[HttpPost]
public ActionResult UpdateAssistanceScheme(YourModelTypeHere model) 
{
   // value is in model.Lang_id
}

foreach (var p in Model)
{
@Html.RadioButtonFor(model => model.Lang_id, "1", Model.Lang_id == '1' ? new { @Checked = "checked" } : null) English
@Html.RadioButtonFor(model => model.Lang_id, "2", Model.Lang_id == '2' ? new { @Checked = "checked" } : null) Hindi
@Html.RadioButtonFor(model => model.Lang_id, "3", Model.Lang_id == '3' ? new { @Checked = "checked" } : null)
}

p is Variable

You didn't think the fact that your code was actually in a loop was relevant enough to mention?

If you want to loop through items in a model you need to use indexes rather than "for each"

@for(int i = 0; i < Model.Count; i++)
{
@Html.RadioButtonFor(model => model[i].Lang_id, "1", Model[i].Lang_id == '1' ? new { @Checked = "checked" } : null) <text>English
@Html.RadioButtonFor(model => model[i].Lang_id, "2", Model[i].Lang_id == '2' ? new { @Checked = "checked" } : null) <text>Hindi
@Html.RadioButtonFor(model => model[i].Lang_id, "3", Model[i].Lang_id == '3' ? new { @Checked = "checked" } : null)
}

Your action will then be

public ActionResult UpdateAssistanceScheme(List<YourModelTypeHere> model)
