Answer 1

As Shubam has explained it, Though I would like to form it as a complete answer

First of all, I would like to let you know that Never Use lowercase letters to name your React Components.So name your component to One instead of one.

Now Comming back to your question:- No This is not Possible, If your app contains few components then it's better to pass the state object as the props, But if your app contains too many components then better to use predictable state containers like Redux or Flux rather than passing state as props.

So you may apply these changes and I hope You will get What You Desire:-

One Component:-

import React, { Component } from 'react';
import Homepage from './homepage';

class One extends React.Component 
{
    constructor()
    {
        super();
        this.state = {
            number:26
        }
    }
    render()
    {
        return(
            <Homepage data={this.state}/>
        );
    }
}

export default One;

Homepage Component:-

import React, { Component } from 'react';


class Homepage extends React.Component 
{

    render()
    {
        console.log("this is homepage",this.props);
        return(
            <div>{this.props.data.number}</div>
        );
    }
}

export default Homepage;
