There are so many questions in your post which was not quite clear to me. Please post one by one so that it will be easy to explain to solve the problems.

Hoping for the clear questions...
 

Whith DHT11 sensor you save:
ADC0808
LM35
HR202

Regards!
 

As you are having basic ideas on this its better to go with the digital sensors for all the parameters which you are going to use. If you are quite experienced with analog then only proceed with analog sensors
 

If it is HR 202 module like this it can be directly interfaced.
Plenty of information is available on net.

I recently did a project with a DHT-11, and I can highly recommend this sensor for humidity. For temperature, it is not as accurate as dedicated temperature sensors.
 

For more precision, you can use his brother DHT22:
DHT11 Maximun Accuray ±2ºC
DHT22/AM2302 Accuray ±0.5ºC

Regards!
